HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 572, 402, 103 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 572, 402, 103 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 572, 402, 103 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 572, 402, 103 is 1.

HCF(572, 402, 103) = 1

Highest Common Factor of 572,402,103 using Euclid's algorithm

Highest Common Factor of 572,402,103 is 1

Step 1: Since 572 > 402, we apply the division lemma to 572 and 402, to get

572 = 402 x 1 + 170

Step 2: Since the reminder 402 ≠ 0, we apply division lemma to 170 and 402, to get

402 = 170 x 2 + 62

Step 3: We consider the new divisor 170 and the new remainder 62, and apply the division lemma to get

170 = 62 x 2 + 46

We consider the new divisor 62 and the new remainder 46,and apply the division lemma to get

62 = 46 x 1 + 16

We consider the new divisor 46 and the new remainder 16,and apply the division lemma to get

46 = 16 x 2 + 14

We consider the new divisor 16 and the new remainder 14,and apply the division lemma to get

16 = 14 x 1 + 2

We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get

14 = 2 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 572 and 402 is 2

Notice that 2 = HCF(14,2) = HCF(16,14) = HCF(46,16) = HCF(62,46) = HCF(170,62) = HCF(402,170) = HCF(572,402) .

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

Step 1: Since 103 > 2, we apply the division lemma to 103 and 2, to get

103 = 2 x 51 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 103 is 1

Notice that 1 = HCF(2,1) = HCF(103,2) .
