HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 405, 676, 602 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 405, 676, 602 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 405, 676, 602 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 405, 676, 602 is 1.

HCF(405, 676, 602) = 1

HCF of 405, 676, 602 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 405, 676, 602 is 1.

Highest Common Factor of 405,676,602 using Euclid's algorithm

Highest Common Factor of 405,676,602 is 1

Step 1: Since 676 > 405, we apply the division lemma to 676 and 405, to get

676 = 405 x 1 + 271

Step 2: Since the reminder 405 ≠ 0, we apply division lemma to 271 and 405, to get

405 = 271 x 1 + 134

Step 3: We consider the new divisor 271 and the new remainder 134, and apply the division lemma to get

271 = 134 x 2 + 3

We consider the new divisor 134 and the new remainder 3,and apply the division lemma to get

134 = 3 x 44 + 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 405 and 676 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(134,3) = HCF(271,134) = HCF(405,271) = HCF(676,405) .

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

Step 1: Since 602 > 1, we apply the division lemma to 602 and 1, to get

602 = 1 x 602 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 602 is 1

Notice that 1 = HCF(602,1) .
