HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 638, 913 i.e. 11 the largest integer that leaves a remainder zero for all numbers.
HCF of 638, 913 is 11 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 638, 913 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 638, 913 is 11.
HCF(638, 913) = 11
HCF of 638, 913 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 638, 913 is 11.
Highest Common Factor of 638,913 is 11
Step 1: Since 913 > 638, we apply the division lemma to 913 and 638, to get
913 = 638 x 1 + 275
Step 2: Since the reminder 638 ≠ 0, we apply division lemma to 275 and 638, to get
638 = 275 x 2 + 88
Step 3: We consider the new divisor 275 and the new remainder 88, and apply the division lemma to get
275 = 88 x 3 + 11
We consider the new divisor 88 and the new remainder 11, and apply the division lemma to get
88 = 11 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 638 and 913 is 11
Notice that 11 = HCF(88,11) = HCF(275,88) = HCF(638,275) = HCF(913,638) .
