HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 69, 79, 747, 759 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 69, 79, 747, 759 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 69, 79, 747, 759 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 69, 79, 747, 759 is 1.

HCF(69, 79, 747, 759) = 1

## HCF of 69, 79, 747, 759 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 69, 79, 747, 759 is 1. ### Highest Common Factor of 69,79,747,759 is 1

Step 1: Since 79 > 69, we apply the division lemma to 79 and 69, to get

79 = 69 x 1 + 10

Step 2: Since the reminder 69 ≠ 0, we apply division lemma to 10 and 69, to get

69 = 10 x 6 + 9

Step 3: We consider the new divisor 10 and the new remainder 9, and apply the division lemma to get

10 = 9 x 1 + 1

We consider the new divisor 9 and the new remainder 1, and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 69 and 79 is 1

Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(69,10) = HCF(79,69) .

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

Step 1: Since 747 > 1, we apply the division lemma to 747 and 1, to get

747 = 1 x 747 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 747 is 1

Notice that 1 = HCF(747,1) .

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

Step 1: Since 759 > 1, we apply the division lemma to 759 and 1, to get

759 = 1 x 759 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 759 is 1

Notice that 1 = HCF(759,1) .
