HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 647, 268 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 647, 268 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 647, 268 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 647, 268 is 1.
HCF(647, 268) = 1
HCF of 647, 268 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 647, 268 is 1.
Highest Common Factor of 647,268 is 1
Step 1: Since 647 > 268, we apply the division lemma to 647 and 268, to get
647 = 268 x 2 + 111
Step 2: Since the reminder 268 ≠ 0, we apply division lemma to 111 and 268, to get
268 = 111 x 2 + 46
Step 3: We consider the new divisor 111 and the new remainder 46, and apply the division lemma to get
111 = 46 x 2 + 19
We consider the new divisor 46 and the new remainder 19,and apply the division lemma to get
46 = 19 x 2 + 8
We consider the new divisor 19 and the new remainder 8,and apply the division lemma to get
19 = 8 x 2 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 647 and 268 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(19,8) = HCF(46,19) = HCF(111,46) = HCF(268,111) = HCF(647,268) .
