HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 634 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 980, 634 is 2 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 980, 634 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 980, 634 is 2.
HCF(980, 634) = 2
HCF of 980, 634 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 980, 634 is 2.
Highest Common Factor of 980,634 is 2
Step 1: Since 980 > 634, we apply the division lemma to 980 and 634, to get
980 = 634 x 1 + 346
Step 2: Since the reminder 634 ≠ 0, we apply division lemma to 346 and 634, to get
634 = 346 x 1 + 288
Step 3: We consider the new divisor 346 and the new remainder 288, and apply the division lemma to get
346 = 288 x 1 + 58
We consider the new divisor 288 and the new remainder 58,and apply the division lemma to get
288 = 58 x 4 + 56
We consider the new divisor 58 and the new remainder 56,and apply the division lemma to get
58 = 56 x 1 + 2
We consider the new divisor 56 and the new remainder 2,and apply the division lemma to get
56 = 2 x 28 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 980 and 634 is 2
Notice that 2 = HCF(56,2) = HCF(58,56) = HCF(288,58) = HCF(346,288) = HCF(634,346) = HCF(980,634) .
