HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 437, 604, 689, 105 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 437, 604, 689, 105 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 437, 604, 689, 105 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 437, 604, 689, 105 is 1.
HCF(437, 604, 689, 105) = 1
HCF of 437, 604, 689, 105 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 437, 604, 689, 105 is 1.
Highest Common Factor of 437,604,689,105 is 1
Step 1: Since 604 > 437, we apply the division lemma to 604 and 437, to get
604 = 437 x 1 + 167
Step 2: Since the reminder 437 ≠ 0, we apply division lemma to 167 and 437, to get
437 = 167 x 2 + 103
Step 3: We consider the new divisor 167 and the new remainder 103, and apply the division lemma to get
167 = 103 x 1 + 64
We consider the new divisor 103 and the new remainder 64,and apply the division lemma to get
103 = 64 x 1 + 39
We consider the new divisor 64 and the new remainder 39,and apply the division lemma to get
64 = 39 x 1 + 25
We consider the new divisor 39 and the new remainder 25,and apply the division lemma to get
39 = 25 x 1 + 14
We consider the new divisor 25 and the new remainder 14,and apply the division lemma to get
25 = 14 x 1 + 11
We consider the new divisor 14 and the new remainder 11,and apply the division lemma to get
14 = 11 x 1 + 3
We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get
11 = 3 x 3 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 437 and 604 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(25,14) = HCF(39,25) = HCF(64,39) = HCF(103,64) = HCF(167,103) = HCF(437,167) = HCF(604,437) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 689 > 1, we apply the division lemma to 689 and 1, to get
689 = 1 x 689 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 689 is 1
Notice that 1 = HCF(689,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 105 > 1, we apply the division lemma to 105 and 1, to get
105 = 1 x 105 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 105 is 1
Notice that 1 = HCF(105,1) .
