HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 609, 790 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 609, 790 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 609, 790 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 609, 790 is 1.

HCF(609, 790) = 1

Highest Common Factor of 609,790 using Euclid's algorithm

Highest Common Factor of 609,790 is 1

Step 1: Since 790 > 609, we apply the division lemma to 790 and 609, to get

790 = 609 x 1 + 181

Step 2: Since the reminder 609 ≠ 0, we apply division lemma to 181 and 609, to get

609 = 181 x 3 + 66

Step 3: We consider the new divisor 181 and the new remainder 66, and apply the division lemma to get

181 = 66 x 2 + 49

We consider the new divisor 66 and the new remainder 49,and apply the division lemma to get

66 = 49 x 1 + 17

We consider the new divisor 49 and the new remainder 17,and apply the division lemma to get

49 = 17 x 2 + 15

We consider the new divisor 17 and the new remainder 15,and apply the division lemma to get

17 = 15 x 1 + 2

We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get

15 = 2 x 7 + 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 609 and 790 is 1

Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(17,15) = HCF(49,17) = HCF(66,49) = HCF(181,66) = HCF(609,181) = HCF(790,609) .
