HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 311, 392, 432, 57 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 311, 392, 432, 57 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 311, 392, 432, 57 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 311, 392, 432, 57 is 1.

HCF(311, 392, 432, 57) = 1

Highest Common Factor of 311,392,432,57 using Euclid's algorithm

Highest Common Factor of 311,392,432,57 is 1

Step 1: Since 392 > 311, we apply the division lemma to 392 and 311, to get

392 = 311 x 1 + 81

Step 2: Since the reminder 311 ≠ 0, we apply division lemma to 81 and 311, to get

311 = 81 x 3 + 68

Step 3: We consider the new divisor 81 and the new remainder 68, and apply the division lemma to get

81 = 68 x 1 + 13

We consider the new divisor 68 and the new remainder 13,and apply the division lemma to get

68 = 13 x 5 + 3

We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get

13 = 3 x 4 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 311 and 392 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(68,13) = HCF(81,68) = HCF(311,81) = HCF(392,311) .

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

Step 1: Since 432 > 1, we apply the division lemma to 432 and 1, to get

432 = 1 x 432 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 432 is 1

Notice that 1 = HCF(432,1) .

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

Step 1: Since 57 > 1, we apply the division lemma to 57 and 1, to get

57 = 1 x 57 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 57 is 1

Notice that 1 = HCF(57,1) .
