HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 742, 479, 564 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 742, 479, 564 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, 479, 564 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, 479, 564 is 1.

HCF(742, 479, 564) = 1

HCF of 742, 479, 564 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 742, 479, 564 is 1.

Highest Common Factor of 742,479,564 using Euclid's algorithm

Highest Common Factor of 742,479,564 is 1

Step 1: Since 742 > 479, we apply the division lemma to 742 and 479, to get

742 = 479 x 1 + 263

Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 263 and 479, to get

479 = 263 x 1 + 216

Step 3: We consider the new divisor 263 and the new remainder 216, and apply the division lemma to get

263 = 216 x 1 + 47

We consider the new divisor 216 and the new remainder 47,and apply the division lemma to get

216 = 47 x 4 + 28

We consider the new divisor 47 and the new remainder 28,and apply the division lemma to get

47 = 28 x 1 + 19

We consider the new divisor 28 and the new remainder 19,and apply the division lemma to get

28 = 19 x 1 + 9

We consider the new divisor 19 and the new remainder 9,and apply the division lemma to get

19 = 9 x 2 + 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 742 and 479 is 1

Notice that 1 = HCF(9,1) = HCF(19,9) = HCF(28,19) = HCF(47,28) = HCF(216,47) = HCF(263,216) = HCF(479,263) = HCF(742,479) .

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

Step 1: Since 564 > 1, we apply the division lemma to 564 and 1, to get

564 = 1 x 564 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 564 is 1

Notice that 1 = HCF(564,1) .
