HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 903, 572 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 903, 572 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 903, 572 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 903, 572 is 1.

HCF(903, 572) = 1

Highest common factor (HCF) of 903, 572 is 1.

Highest Common Factor of 903,572 using Euclid's algorithm

Highest Common Factor of 903,572 is 1

Step 1: Since 903 > 572, we apply the division lemma to 903 and 572, to get

903 = 572 x 1 + 331

Step 2: Since the reminder 572 ≠ 0, we apply division lemma to 331 and 572, to get

572 = 331 x 1 + 241

Step 3: We consider the new divisor 331 and the new remainder 241, and apply the division lemma to get

331 = 241 x 1 + 90

We consider the new divisor 241 and the new remainder 90,and apply the division lemma to get

241 = 90 x 2 + 61

We consider the new divisor 90 and the new remainder 61,and apply the division lemma to get

90 = 61 x 1 + 29

We consider the new divisor 61 and the new remainder 29,and apply the division lemma to get

61 = 29 x 2 + 3

We consider the new divisor 29 and the new remainder 3,and apply the division lemma to get

29 = 3 x 9 + 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 903 and 572 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(29,3) = HCF(61,29) = HCF(90,61) = HCF(241,90) = HCF(331,241) = HCF(572,331) = HCF(903,572) .
