HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 76, 739, 70 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 76, 739, 70 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 76, 739, 70 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 76, 739, 70 is 1.

HCF(76, 739, 70) = 1

Highest common factor (HCF) of 76, 739, 70 is 1.

Highest Common Factor of 76,739,70 using Euclid's algorithm

Highest Common Factor of 76,739,70 is 1

Step 1: Since 739 > 76, we apply the division lemma to 739 and 76, to get

739 = 76 x 9 + 55

Step 2: Since the reminder 76 ≠ 0, we apply division lemma to 55 and 76, to get

76 = 55 x 1 + 21

Step 3: We consider the new divisor 55 and the new remainder 21, and apply the division lemma to get

55 = 21 x 2 + 13

We consider the new divisor 21 and the new remainder 13,and apply the division lemma to get

21 = 13 x 1 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 76 and 739 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(21,13) = HCF(55,21) = HCF(76,55) = HCF(739,76) .

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

Step 1: Since 70 > 1, we apply the division lemma to 70 and 1, to get

70 = 1 x 70 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 70 is 1

Notice that 1 = HCF(70,1) .
