HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 636, 97854 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 636, 97854 is 6 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, 97854 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, 97854 is 6.
HCF(636, 97854) = 6
HCF of 636, 97854 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, 97854 is 6.
Highest Common Factor of 636,97854 is 6
Step 1: Since 97854 > 636, we apply the division lemma to 97854 and 636, to get
97854 = 636 x 153 + 546
Step 2: Since the reminder 636 ≠ 0, we apply division lemma to 546 and 636, to get
636 = 546 x 1 + 90
Step 3: We consider the new divisor 546 and the new remainder 90, and apply the division lemma to get
546 = 90 x 6 + 6
We consider the new divisor 90 and the new remainder 6, and apply the division lemma to get
90 = 6 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 636 and 97854 is 6
Notice that 6 = HCF(90,6) = HCF(546,90) = HCF(636,546) = HCF(97854,636) .
