HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 374, 617 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 374, 617 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 374, 617 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 374, 617 is 1.

HCF(374, 617) = 1

Highest common factor (HCF) of 374, 617 is 1.

Highest Common Factor of 374,617 using Euclid's algorithm

Highest Common Factor of 374,617 is 1

Step 1: Since 617 > 374, we apply the division lemma to 617 and 374, to get

617 = 374 x 1 + 243

Step 2: Since the reminder 374 ≠ 0, we apply division lemma to 243 and 374, to get

374 = 243 x 1 + 131

Step 3: We consider the new divisor 243 and the new remainder 131, and apply the division lemma to get

243 = 131 x 1 + 112

We consider the new divisor 131 and the new remainder 112,and apply the division lemma to get

131 = 112 x 1 + 19

We consider the new divisor 112 and the new remainder 19,and apply the division lemma to get

112 = 19 x 5 + 17

We consider the new divisor 19 and the new remainder 17,and apply the division lemma to get

19 = 17 x 1 + 2

We consider the new divisor 17 and the new remainder 2,and apply the division lemma to get

17 = 2 x 8 + 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 374 and 617 is 1

Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(19,17) = HCF(112,19) = HCF(131,112) = HCF(243,131) = HCF(374,243) = HCF(617,374) .
