HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 436, 272, 604, 623 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 436, 272, 604, 623 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 436, 272, 604, 623 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 436, 272, 604, 623 is 1.
HCF(436, 272, 604, 623) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 436, 272, 604, 623 is 1.
Step 1: Since 436 > 272, we apply the division lemma to 436 and 272, to get
436 = 272 x 1 + 164
Step 2: Since the reminder 272 ≠ 0, we apply division lemma to 164 and 272, to get
272 = 164 x 1 + 108
Step 3: We consider the new divisor 164 and the new remainder 108, and apply the division lemma to get
164 = 108 x 1 + 56
We consider the new divisor 108 and the new remainder 56,and apply the division lemma to get
108 = 56 x 1 + 52
We consider the new divisor 56 and the new remainder 52,and apply the division lemma to get
56 = 52 x 1 + 4
We consider the new divisor 52 and the new remainder 4,and apply the division lemma to get
52 = 4 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 436 and 272 is 4
Notice that 4 = HCF(52,4) = HCF(56,52) = HCF(108,56) = HCF(164,108) = HCF(272,164) = HCF(436,272) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 604 > 4, we apply the division lemma to 604 and 4, to get
604 = 4 x 151 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 604 is 4
Notice that 4 = HCF(604,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 623 > 4, we apply the division lemma to 623 and 4, to get
623 = 4 x 155 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 623 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(623,4) .
Here are some samples of HCF using Euclid's Algorithm calculations.
