HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 667, 471, 972 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 667, 471, 972 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 667, 471, 972 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 667, 471, 972 is 1.

HCF(667, 471, 972) = 1

HCF of 667, 471, 972 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 667, 471, 972 is 1.

Highest Common Factor of 667,471,972 using Euclid's algorithm

Highest Common Factor of 667,471,972 is 1

Step 1: Since 667 > 471, we apply the division lemma to 667 and 471, to get

667 = 471 x 1 + 196

Step 2: Since the reminder 471 ≠ 0, we apply division lemma to 196 and 471, to get

471 = 196 x 2 + 79

Step 3: We consider the new divisor 196 and the new remainder 79, and apply the division lemma to get

196 = 79 x 2 + 38

We consider the new divisor 79 and the new remainder 38,and apply the division lemma to get

79 = 38 x 2 + 3

We consider the new divisor 38 and the new remainder 3,and apply the division lemma to get

38 = 3 x 12 + 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 667 and 471 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(38,3) = HCF(79,38) = HCF(196,79) = HCF(471,196) = HCF(667,471) .

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

Step 1: Since 972 > 1, we apply the division lemma to 972 and 1, to get

972 = 1 x 972 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 972 is 1

Notice that 1 = HCF(972,1) .
