HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 397, 295, 654 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 397, 295, 654 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 397, 295, 654 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 397, 295, 654 is 1.

HCF(397, 295, 654) = 1

HCF of 397, 295, 654 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 397, 295, 654 is 1.

Highest Common Factor of 397,295,654 using Euclid's algorithm

Highest Common Factor of 397,295,654 is 1

Step 1: Since 397 > 295, we apply the division lemma to 397 and 295, to get

397 = 295 x 1 + 102

Step 2: Since the reminder 295 ≠ 0, we apply division lemma to 102 and 295, to get

295 = 102 x 2 + 91

Step 3: We consider the new divisor 102 and the new remainder 91, and apply the division lemma to get

102 = 91 x 1 + 11

We consider the new divisor 91 and the new remainder 11,and apply the division lemma to get

91 = 11 x 8 + 3

We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get

11 = 3 x 3 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 397 and 295 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(91,11) = HCF(102,91) = HCF(295,102) = HCF(397,295) .

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

Step 1: Since 654 > 1, we apply the division lemma to 654 and 1, to get

654 = 1 x 654 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 654 is 1

Notice that 1 = HCF(654,1) .
