HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 647, 955, 418 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 647, 955, 418 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, 955, 418 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, 955, 418 is 1.

HCF(647, 955, 418) = 1

HCF of 647, 955, 418 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 647, 955, 418 is 1.

Highest Common Factor of 647,955,418 using Euclid's algorithm

Highest Common Factor of 647,955,418 is 1

Step 1: Since 955 > 647, we apply the division lemma to 955 and 647, to get

955 = 647 x 1 + 308

Step 2: Since the reminder 647 ≠ 0, we apply division lemma to 308 and 647, to get

647 = 308 x 2 + 31

Step 3: We consider the new divisor 308 and the new remainder 31, and apply the division lemma to get

308 = 31 x 9 + 29

We consider the new divisor 31 and the new remainder 29,and apply the division lemma to get

31 = 29 x 1 + 2

We consider the new divisor 29 and the new remainder 2,and apply the division lemma to get

29 = 2 x 14 + 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 955 is 1

Notice that 1 = HCF(2,1) = HCF(29,2) = HCF(31,29) = HCF(308,31) = HCF(647,308) = HCF(955,647) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 418 > 1, we apply the division lemma to 418 and 1, to get

418 = 1 x 418 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 418 is 1

Notice that 1 = HCF(418,1) .
