HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 453, 355 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 453, 355 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 453, 355 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 453, 355 is 1.

HCF(453, 355) = 1

Highest common factor (HCF) of 453, 355 is 1.

Highest Common Factor of 453,355 using Euclid's algorithm

Highest Common Factor of 453,355 is 1

Step 1: Since 453 > 355, we apply the division lemma to 453 and 355, to get

453 = 355 x 1 + 98

Step 2: Since the reminder 355 ≠ 0, we apply division lemma to 98 and 355, to get

355 = 98 x 3 + 61

Step 3: We consider the new divisor 98 and the new remainder 61, and apply the division lemma to get

98 = 61 x 1 + 37

We consider the new divisor 61 and the new remainder 37,and apply the division lemma to get

61 = 37 x 1 + 24

We consider the new divisor 37 and the new remainder 24,and apply the division lemma to get

37 = 24 x 1 + 13

We consider the new divisor 24 and the new remainder 13,and apply the division lemma to get

24 = 13 x 1 + 11

We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get

13 = 11 x 1 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 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 453 and 355 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(24,13) = HCF(37,24) = HCF(61,37) = HCF(98,61) = HCF(355,98) = HCF(453,355) .
