HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 637, 980 i.e. 49 the largest integer that leaves a remainder zero for all numbers.
HCF of 637, 980 is 49 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 637, 980 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 637, 980 is 49.
HCF(637, 980) = 49
HCF of 637, 980 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 637, 980 is 49.
Highest Common Factor of 637,980 is 49
Step 1: Since 980 > 637, we apply the division lemma to 980 and 637, to get
980 = 637 x 1 + 343
Step 2: Since the reminder 637 ≠ 0, we apply division lemma to 343 and 637, to get
637 = 343 x 1 + 294
Step 3: We consider the new divisor 343 and the new remainder 294, and apply the division lemma to get
343 = 294 x 1 + 49
We consider the new divisor 294 and the new remainder 49, and apply the division lemma to get
294 = 49 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 49, the HCF of 637 and 980 is 49
Notice that 49 = HCF(294,49) = HCF(343,294) = HCF(637,343) = HCF(980,637) .
