HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 792, 971, 415 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 792, 971, 415 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 792, 971, 415 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 792, 971, 415 is 1.

HCF(792, 971, 415) = 1

Highest common factor (HCF) of 792, 971, 415 is 1.

Highest Common Factor of 792,971,415 using Euclid's algorithm

Highest Common Factor of 792,971,415 is 1

Step 1: Since 971 > 792, we apply the division lemma to 971 and 792, to get

971 = 792 x 1 + 179

Step 2: Since the reminder 792 ≠ 0, we apply division lemma to 179 and 792, to get

792 = 179 x 4 + 76

Step 3: We consider the new divisor 179 and the new remainder 76, and apply the division lemma to get

179 = 76 x 2 + 27

We consider the new divisor 76 and the new remainder 27,and apply the division lemma to get

76 = 27 x 2 + 22

We consider the new divisor 27 and the new remainder 22,and apply the division lemma to get

27 = 22 x 1 + 5

We consider the new divisor 22 and the new remainder 5,and apply the division lemma to get

22 = 5 x 4 + 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 792 and 971 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(22,5) = HCF(27,22) = HCF(76,27) = HCF(179,76) = HCF(792,179) = HCF(971,792) .

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

Step 1: Since 415 > 1, we apply the division lemma to 415 and 1, to get

415 = 1 x 415 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 415 is 1

Notice that 1 = HCF(415,1) .
