HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 931, 663, 647 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 931, 663, 647 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 931, 663, 647 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 931, 663, 647 is 1.
HCF(931, 663, 647) = 1
HCF of 931, 663, 647 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 931, 663, 647 is 1.
Highest Common Factor of 931,663,647 is 1
Step 1: Since 931 > 663, we apply the division lemma to 931 and 663, to get
931 = 663 x 1 + 268
Step 2: Since the reminder 663 ≠ 0, we apply division lemma to 268 and 663, to get
663 = 268 x 2 + 127
Step 3: We consider the new divisor 268 and the new remainder 127, and apply the division lemma to get
268 = 127 x 2 + 14
We consider the new divisor 127 and the new remainder 14,and apply the division lemma to get
127 = 14 x 9 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 931 and 663 is 1
Notice that 1 = HCF(14,1) = HCF(127,14) = HCF(268,127) = HCF(663,268) = HCF(931,663) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 647 > 1, we apply the division lemma to 647 and 1, to get
647 = 1 x 647 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 647 is 1
Notice that 1 = HCF(647,1) .
