HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 636, 768 i.e. 12 the largest integer that leaves a remainder zero for all numbers.
HCF of 636, 768 is 12 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, 768 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, 768 is 12.
HCF(636, 768) = 12
HCF of 636, 768 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, 768 is 12.
Highest Common Factor of 636,768 is 12
Step 1: Since 768 > 636, we apply the division lemma to 768 and 636, to get
768 = 636 x 1 + 132
Step 2: Since the reminder 636 ≠ 0, we apply division lemma to 132 and 636, to get
636 = 132 x 4 + 108
Step 3: We consider the new divisor 132 and the new remainder 108, and apply the division lemma to get
132 = 108 x 1 + 24
We consider the new divisor 108 and the new remainder 24,and apply the division lemma to get
108 = 24 x 4 + 12
We consider the new divisor 24 and the new remainder 12,and apply the division lemma to get
24 = 12 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 636 and 768 is 12
Notice that 12 = HCF(24,12) = HCF(108,24) = HCF(132,108) = HCF(636,132) = HCF(768,636) .
