HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 502, 349, 57 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 502, 349, 57 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 502, 349, 57 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 502, 349, 57 is 1.

HCF(502, 349, 57) = 1

Highest common factor (HCF) of 502, 349, 57 is 1.

Highest Common Factor of 502,349,57 using Euclid's algorithm

Highest Common Factor of 502,349,57 is 1

Step 1: Since 502 > 349, we apply the division lemma to 502 and 349, to get

502 = 349 x 1 + 153

Step 2: Since the reminder 349 ≠ 0, we apply division lemma to 153 and 349, to get

349 = 153 x 2 + 43

Step 3: We consider the new divisor 153 and the new remainder 43, and apply the division lemma to get

153 = 43 x 3 + 24

We consider the new divisor 43 and the new remainder 24,and apply the division lemma to get

43 = 24 x 1 + 19

We consider the new divisor 24 and the new remainder 19,and apply the division lemma to get

24 = 19 x 1 + 5

We consider the new divisor 19 and the new remainder 5,and apply the division lemma to get

19 = 5 x 3 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 502 and 349 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(19,5) = HCF(24,19) = HCF(43,24) = HCF(153,43) = HCF(349,153) = HCF(502,349) .

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

Step 1: Since 57 > 1, we apply the division lemma to 57 and 1, to get

57 = 1 x 57 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 57 is 1

Notice that 1 = HCF(57,1) .
