HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 240, 636 i.e. 12 the largest integer that leaves a remainder zero for all numbers.
HCF of 240, 636 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 240, 636 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 240, 636 is 12.
HCF(240, 636) = 12
HCF of 240, 636 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 240, 636 is 12.
Highest Common Factor of 240,636 is 12
Step 1: Since 636 > 240, we apply the division lemma to 636 and 240, to get
636 = 240 x 2 + 156
Step 2: Since the reminder 240 ≠ 0, we apply division lemma to 156 and 240, to get
240 = 156 x 1 + 84
Step 3: We consider the new divisor 156 and the new remainder 84, and apply the division lemma to get
156 = 84 x 1 + 72
We consider the new divisor 84 and the new remainder 72,and apply the division lemma to get
84 = 72 x 1 + 12
We consider the new divisor 72 and the new remainder 12,and apply the division lemma to get
72 = 12 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 240 and 636 is 12
Notice that 12 = HCF(72,12) = HCF(84,72) = HCF(156,84) = HCF(240,156) = HCF(636,240) .
