HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 631, 638 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 631, 638 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 631, 638 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 631, 638 is 1.
HCF(631, 638) = 1
HCF of 631, 638 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 631, 638 is 1.
Highest Common Factor of 631,638 is 1
Step 1: Since 638 > 631, we apply the division lemma to 638 and 631, to get
638 = 631 x 1 + 7
Step 2: Since the reminder 631 ≠ 0, we apply division lemma to 7 and 631, to get
631 = 7 x 90 + 1
Step 3: We consider the new divisor 7 and the new remainder 1, and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 631 and 638 is 1
Notice that 1 = HCF(7,1) = HCF(631,7) = HCF(638,631) .
