HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 742, 615, 579 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 742, 615, 579 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 742, 615, 579 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 742, 615, 579 is 1.

HCF(742, 615, 579) = 1

Highest common factor (HCF) of 742, 615, 579 is 1.

Highest Common Factor of 742,615,579 using Euclid's algorithm

Highest Common Factor of 742,615,579 is 1

Step 1: Since 742 > 615, we apply the division lemma to 742 and 615, to get

742 = 615 x 1 + 127

Step 2: Since the reminder 615 ≠ 0, we apply division lemma to 127 and 615, to get

615 = 127 x 4 + 107

Step 3: We consider the new divisor 127 and the new remainder 107, and apply the division lemma to get

127 = 107 x 1 + 20

We consider the new divisor 107 and the new remainder 20,and apply the division lemma to get

107 = 20 x 5 + 7

We consider the new divisor 20 and the new remainder 7,and apply the division lemma to get

20 = 7 x 2 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 742 and 615 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(20,7) = HCF(107,20) = HCF(127,107) = HCF(615,127) = HCF(742,615) .

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

Step 1: Since 579 > 1, we apply the division lemma to 579 and 1, to get

579 = 1 x 579 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 579 is 1

Notice that 1 = HCF(579,1) .
