HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 369, 254, 656 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 369, 254, 656 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 369, 254, 656 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 369, 254, 656 is 1.

HCF(369, 254, 656) = 1

HCF of 369, 254, 656 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 369, 254, 656 is 1.

Highest Common Factor of 369,254,656 using Euclid's algorithm

Highest Common Factor of 369,254,656 is 1

Step 1: Since 369 > 254, we apply the division lemma to 369 and 254, to get

369 = 254 x 1 + 115

Step 2: Since the reminder 254 ≠ 0, we apply division lemma to 115 and 254, to get

254 = 115 x 2 + 24

Step 3: We consider the new divisor 115 and the new remainder 24, and apply the division lemma to get

115 = 24 x 4 + 19

We consider the new divisor 24 and the new remainder 19,and apply the division lemma to get

24 = 19 x 1 + 5

We consider the new divisor 19 and the new remainder 5,and apply the division lemma to get

19 = 5 x 3 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 369 and 254 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(19,5) = HCF(24,19) = HCF(115,24) = HCF(254,115) = HCF(369,254) .

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

Step 1: Since 656 > 1, we apply the division lemma to 656 and 1, to get

656 = 1 x 656 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 656 is 1

Notice that 1 = HCF(656,1) .
