HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 418, 674, 39 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 418, 674, 39 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 418, 674, 39 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 418, 674, 39 is 1.

HCF(418, 674, 39) = 1

Highest common factor (HCF) of 418, 674, 39 is 1.

Highest Common Factor of 418,674,39 using Euclid's algorithm

Highest Common Factor of 418,674,39 is 1

Step 1: Since 674 > 418, we apply the division lemma to 674 and 418, to get

674 = 418 x 1 + 256

Step 2: Since the reminder 418 ≠ 0, we apply division lemma to 256 and 418, to get

418 = 256 x 1 + 162

Step 3: We consider the new divisor 256 and the new remainder 162, and apply the division lemma to get

256 = 162 x 1 + 94

We consider the new divisor 162 and the new remainder 94,and apply the division lemma to get

162 = 94 x 1 + 68

We consider the new divisor 94 and the new remainder 68,and apply the division lemma to get

94 = 68 x 1 + 26

We consider the new divisor 68 and the new remainder 26,and apply the division lemma to get

68 = 26 x 2 + 16

We consider the new divisor 26 and the new remainder 16,and apply the division lemma to get

26 = 16 x 1 + 10

We consider the new divisor 16 and the new remainder 10,and apply the division lemma to get

16 = 10 x 1 + 6

We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get

10 = 6 x 1 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 418 and 674 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(16,10) = HCF(26,16) = HCF(68,26) = HCF(94,68) = HCF(162,94) = HCF(256,162) = HCF(418,256) = HCF(674,418) .

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

Step 1: Since 39 > 2, we apply the division lemma to 39 and 2, to get

39 = 2 x 19 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 39 is 1

Notice that 1 = HCF(2,1) = HCF(39,2) .
