HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 244, 678, 451 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 244, 678, 451 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 244, 678, 451 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 244, 678, 451 is 1.

HCF(244, 678, 451) = 1

Highest common factor (HCF) of 244, 678, 451 is 1.

Highest Common Factor of 244,678,451 using Euclid's algorithm

Highest Common Factor of 244,678,451 is 1

Step 1: Since 678 > 244, we apply the division lemma to 678 and 244, to get

678 = 244 x 2 + 190

Step 2: Since the reminder 244 ≠ 0, we apply division lemma to 190 and 244, to get

244 = 190 x 1 + 54

Step 3: We consider the new divisor 190 and the new remainder 54, and apply the division lemma to get

190 = 54 x 3 + 28

We consider the new divisor 54 and the new remainder 28,and apply the division lemma to get

54 = 28 x 1 + 26

We consider the new divisor 28 and the new remainder 26,and apply the division lemma to get

28 = 26 x 1 + 2

We consider the new divisor 26 and the new remainder 2,and apply the division lemma to get

26 = 2 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 244 and 678 is 2

Notice that 2 = HCF(26,2) = HCF(28,26) = HCF(54,28) = HCF(190,54) = HCF(244,190) = HCF(678,244) .

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

Step 1: Since 451 > 2, we apply the division lemma to 451 and 2, to get

451 = 2 x 225 + 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 451 is 1

Notice that 1 = HCF(2,1) = HCF(451,2) .
