HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 636, 720 i.e. 12 the largest integer that leaves a remainder zero for all numbers.
HCF of 636, 720 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, 720 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, 720 is 12.
HCF(636, 720) = 12
HCF of 636, 720 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, 720 is 12.
Highest Common Factor of 636,720 is 12
Step 1: Since 720 > 636, we apply the division lemma to 720 and 636, to get
720 = 636 x 1 + 84
Step 2: Since the reminder 636 ≠ 0, we apply division lemma to 84 and 636, to get
636 = 84 x 7 + 48
Step 3: We consider the new divisor 84 and the new remainder 48, and apply the division lemma to get
84 = 48 x 1 + 36
We consider the new divisor 48 and the new remainder 36,and apply the division lemma to get
48 = 36 x 1 + 12
We consider the new divisor 36 and the new remainder 12,and apply the division lemma to get
36 = 12 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 636 and 720 is 12
Notice that 12 = HCF(36,12) = HCF(48,36) = HCF(84,48) = HCF(636,84) = HCF(720,636) .
