HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 329, 387, 637 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 329, 387, 637 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 329, 387, 637 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 329, 387, 637 is 1.
HCF(329, 387, 637) = 1
HCF of 329, 387, 637 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 329, 387, 637 is 1.
Highest Common Factor of 329,387,637 is 1
Step 1: Since 387 > 329, we apply the division lemma to 387 and 329, to get
387 = 329 x 1 + 58
Step 2: Since the reminder 329 ≠ 0, we apply division lemma to 58 and 329, to get
329 = 58 x 5 + 39
Step 3: We consider the new divisor 58 and the new remainder 39, and apply the division lemma to get
58 = 39 x 1 + 19
We consider the new divisor 39 and the new remainder 19,and apply the division lemma to get
39 = 19 x 2 + 1
We consider the new divisor 19 and the new remainder 1,and apply the division lemma to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 329 and 387 is 1
Notice that 1 = HCF(19,1) = HCF(39,19) = HCF(58,39) = HCF(329,58) = HCF(387,329) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 637 > 1, we apply the division lemma to 637 and 1, to get
637 = 1 x 637 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 637 is 1
Notice that 1 = HCF(637,1) .
