HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 408, 705, 839, 167 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 408, 705, 839, 167 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 408, 705, 839, 167 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 408, 705, 839, 167 is 1.
HCF(408, 705, 839, 167) = 1
HCF of 408, 705, 839, 167 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 408, 705, 839, 167 is 1.
Highest Common Factor of 408,705,839,167 is 1
Step 1: Since 705 > 408, we apply the division lemma to 705 and 408, to get
705 = 408 x 1 + 297
Step 2: Since the reminder 408 ≠ 0, we apply division lemma to 297 and 408, to get
408 = 297 x 1 + 111
Step 3: We consider the new divisor 297 and the new remainder 111, and apply the division lemma to get
297 = 111 x 2 + 75
We consider the new divisor 111 and the new remainder 75,and apply the division lemma to get
111 = 75 x 1 + 36
We consider the new divisor 75 and the new remainder 36,and apply the division lemma to get
75 = 36 x 2 + 3
We consider the new divisor 36 and the new remainder 3,and apply the division lemma to get
36 = 3 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 408 and 705 is 3
Notice that 3 = HCF(36,3) = HCF(75,36) = HCF(111,75) = HCF(297,111) = HCF(408,297) = HCF(705,408) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 839 > 3, we apply the division lemma to 839 and 3, to get
839 = 3 x 279 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 839 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(839,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 167 > 1, we apply the division lemma to 167 and 1, to get
167 = 1 x 167 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 167 is 1
Notice that 1 = HCF(167,1) .
