HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 637, 731, 677 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 637, 731, 677 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, 731, 677 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, 731, 677 is 1.
HCF(637, 731, 677) = 1
HCF of 637, 731, 677 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 637, 731, 677 is 1.
Highest Common Factor of 637,731,677 is 1
Step 1: Since 731 > 637, we apply the division lemma to 731 and 637, to get
731 = 637 x 1 + 94
Step 2: Since the reminder 637 ≠ 0, we apply division lemma to 94 and 637, to get
637 = 94 x 6 + 73
Step 3: We consider the new divisor 94 and the new remainder 73, and apply the division lemma to get
94 = 73 x 1 + 21
We consider the new divisor 73 and the new remainder 21,and apply the division lemma to get
73 = 21 x 3 + 10
We consider the new divisor 21 and the new remainder 10,and apply the division lemma to get
21 = 10 x 2 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 637 and 731 is 1
Notice that 1 = HCF(10,1) = HCF(21,10) = HCF(73,21) = HCF(94,73) = HCF(637,94) = HCF(731,637) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 677 > 1, we apply the division lemma to 677 and 1, to get
677 = 1 x 677 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 677 is 1
Notice that 1 = HCF(677,1) .
