HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 647, 607 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 647, 607 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, 607 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, 607 is 1.
HCF(647, 607) = 1
HCF of 647, 607 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, 607 is 1.
Highest Common Factor of 647,607 is 1
Step 1: Since 647 > 607, we apply the division lemma to 647 and 607, to get
647 = 607 x 1 + 40
Step 2: Since the reminder 607 ≠ 0, we apply division lemma to 40 and 607, to get
607 = 40 x 15 + 7
Step 3: We consider the new divisor 40 and the new remainder 7, and apply the division lemma to get
40 = 7 x 5 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 607 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(40,7) = HCF(607,40) = HCF(647,607) .
