HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 637, 72243 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 637, 72243 is 1 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 637, 72243 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 637, 72243 is 1.
HCF(637, 72243) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 637, 72243 is 1.
Step 1: Since 72243 > 637, we apply the division lemma to 72243 and 637, to get
72243 = 637 x 113 + 262
Step 2: Since the reminder 637 ≠ 0, we apply division lemma to 262 and 637, to get
637 = 262 x 2 + 113
Step 3: We consider the new divisor 262 and the new remainder 113, and apply the division lemma to get
262 = 113 x 2 + 36
We consider the new divisor 113 and the new remainder 36,and apply the division lemma to get
113 = 36 x 3 + 5
We consider the new divisor 36 and the new remainder 5,and apply the division lemma to get
36 = 5 x 7 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 637 and 72243 is 1
Notice that 1 = HCF(5,1) = HCF(36,5) = HCF(113,36) = HCF(262,113) = HCF(637,262) = HCF(72243,637) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
