HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 417, 570 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 417, 570 is 3 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 417, 570 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 417, 570 is 3.

HCF(417, 570) = 3

Highest Common Factor of 417,570 using Euclid's algorithm

Highest Common Factor of 417,570 is 3

Step 1: Since 570 > 417, we apply the division lemma to 570 and 417, to get

570 = 417 x 1 + 153

Step 2: Since the reminder 417 ≠ 0, we apply division lemma to 153 and 417, to get

417 = 153 x 2 + 111

Step 3: We consider the new divisor 153 and the new remainder 111, and apply the division lemma to get

153 = 111 x 1 + 42

We consider the new divisor 111 and the new remainder 42,and apply the division lemma to get

111 = 42 x 2 + 27

We consider the new divisor 42 and the new remainder 27,and apply the division lemma to get

42 = 27 x 1 + 15

We consider the new divisor 27 and the new remainder 15,and apply the division lemma to get

27 = 15 x 1 + 12

We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get

15 = 12 x 1 + 3

We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get

12 = 3 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 417 and 570 is 3

Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(27,15) = HCF(42,27) = HCF(111,42) = HCF(153,111) = HCF(417,153) = HCF(570,417) .
