HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 602, 961, 428 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 602, 961, 428 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 602, 961, 428 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 602, 961, 428 is 1.

HCF(602, 961, 428) = 1

HCF of 602, 961, 428 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 602, 961, 428 is 1.

Highest Common Factor of 602,961,428 using Euclid's algorithm

Highest Common Factor of 602,961,428 is 1

Step 1: Since 961 > 602, we apply the division lemma to 961 and 602, to get

961 = 602 x 1 + 359

Step 2: Since the reminder 602 ≠ 0, we apply division lemma to 359 and 602, to get

602 = 359 x 1 + 243

Step 3: We consider the new divisor 359 and the new remainder 243, and apply the division lemma to get

359 = 243 x 1 + 116

We consider the new divisor 243 and the new remainder 116,and apply the division lemma to get

243 = 116 x 2 + 11

We consider the new divisor 116 and the new remainder 11,and apply the division lemma to get

116 = 11 x 10 + 6

We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get

11 = 6 x 1 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 602 and 961 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(116,11) = HCF(243,116) = HCF(359,243) = HCF(602,359) = HCF(961,602) .

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

Step 1: Since 428 > 1, we apply the division lemma to 428 and 1, to get

428 = 1 x 428 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 428 is 1

Notice that 1 = HCF(428,1) .
