HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 938, 674, 435, 811 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 938, 674, 435, 811 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 938, 674, 435, 811 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 938, 674, 435, 811 is 1.

HCF(938, 674, 435, 811) = 1

Highest common factor (HCF) of 938, 674, 435, 811 is 1.

Highest Common Factor of 938,674,435,811 using Euclid's algorithm

Highest Common Factor of 938,674,435,811 is 1

Step 1: Since 938 > 674, we apply the division lemma to 938 and 674, to get

938 = 674 x 1 + 264

Step 2: Since the reminder 674 ≠ 0, we apply division lemma to 264 and 674, to get

674 = 264 x 2 + 146

Step 3: We consider the new divisor 264 and the new remainder 146, and apply the division lemma to get

264 = 146 x 1 + 118

We consider the new divisor 146 and the new remainder 118,and apply the division lemma to get

146 = 118 x 1 + 28

We consider the new divisor 118 and the new remainder 28,and apply the division lemma to get

118 = 28 x 4 + 6

We consider the new divisor 28 and the new remainder 6,and apply the division lemma to get

28 = 6 x 4 + 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 938 and 674 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(28,6) = HCF(118,28) = HCF(146,118) = HCF(264,146) = HCF(674,264) = HCF(938,674) .

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

Step 1: Since 435 > 2, we apply the division lemma to 435 and 2, to get

435 = 2 x 217 + 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 435 is 1

Notice that 1 = HCF(2,1) = HCF(435,2) .

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

Step 1: Since 811 > 1, we apply the division lemma to 811 and 1, to get

811 = 1 x 811 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 811 is 1

Notice that 1 = HCF(811,1) .
