HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 636, 61563 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 636, 61563 is 3 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 636, 61563 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 636, 61563 is 3.
HCF(636, 61563) = 3
HCF of 636, 61563 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 636, 61563 is 3.
Highest Common Factor of 636,61563 is 3
Step 1: Since 61563 > 636, we apply the division lemma to 61563 and 636, to get
61563 = 636 x 96 + 507
Step 2: Since the reminder 636 ≠ 0, we apply division lemma to 507 and 636, to get
636 = 507 x 1 + 129
Step 3: We consider the new divisor 507 and the new remainder 129, and apply the division lemma to get
507 = 129 x 3 + 120
We consider the new divisor 129 and the new remainder 120,and apply the division lemma to get
129 = 120 x 1 + 9
We consider the new divisor 120 and the new remainder 9,and apply the division lemma to get
120 = 9 x 13 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 636 and 61563 is 3
Notice that 3 = HCF(9,3) = HCF(120,9) = HCF(129,120) = HCF(507,129) = HCF(636,507) = HCF(61563,636) .
