HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 454, 939, 256 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 454, 939, 256 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 454, 939, 256 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 454, 939, 256 is 1.

HCF(454, 939, 256) = 1

HCF of 454, 939, 256 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 454, 939, 256 is 1.

Highest Common Factor of 454,939,256 using Euclid's algorithm

Highest Common Factor of 454,939,256 is 1

Step 1: Since 939 > 454, we apply the division lemma to 939 and 454, to get

939 = 454 x 2 + 31

Step 2: Since the reminder 454 ≠ 0, we apply division lemma to 31 and 454, to get

454 = 31 x 14 + 20

Step 3: We consider the new divisor 31 and the new remainder 20, and apply the division lemma to get

31 = 20 x 1 + 11

We consider the new divisor 20 and the new remainder 11,and apply the division lemma to get

20 = 11 x 1 + 9

We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get

11 = 9 x 1 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 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 454 and 939 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(20,11) = HCF(31,20) = HCF(454,31) = HCF(939,454) .

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

Step 1: Since 256 > 1, we apply the division lemma to 256 and 1, to get

256 = 1 x 256 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 256 is 1

Notice that 1 = HCF(256,1) .
