HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 657, 998, 609, 253 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 657, 998, 609, 253 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 657, 998, 609, 253 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 657, 998, 609, 253 is 1.

HCF(657, 998, 609, 253) = 1

Highest common factor (HCF) of 657, 998, 609, 253 is 1.

Highest Common Factor of 657,998,609,253 using Euclid's algorithm

Highest Common Factor of 657,998,609,253 is 1

Step 1: Since 998 > 657, we apply the division lemma to 998 and 657, to get

998 = 657 x 1 + 341

Step 2: Since the reminder 657 ≠ 0, we apply division lemma to 341 and 657, to get

657 = 341 x 1 + 316

Step 3: We consider the new divisor 341 and the new remainder 316, and apply the division lemma to get

341 = 316 x 1 + 25

We consider the new divisor 316 and the new remainder 25,and apply the division lemma to get

316 = 25 x 12 + 16

We consider the new divisor 25 and the new remainder 16,and apply the division lemma to get

25 = 16 x 1 + 9

We consider the new divisor 16 and the new remainder 9,and apply the division lemma to get

16 = 9 x 1 + 7

We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get

9 = 7 x 1 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 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 657 and 998 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(16,9) = HCF(25,16) = HCF(316,25) = HCF(341,316) = HCF(657,341) = HCF(998,657) .

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

Step 1: Since 609 > 1, we apply the division lemma to 609 and 1, to get

609 = 1 x 609 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 609 is 1

Notice that 1 = HCF(609,1) .

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

Step 1: Since 253 > 1, we apply the division lemma to 253 and 1, to get

253 = 1 x 253 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 253 is 1

Notice that 1 = HCF(253,1) .
