HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 216, 602, 981 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 216, 602, 981 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 216, 602, 981 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 216, 602, 981 is 1.

HCF(216, 602, 981) = 1

Highest Common Factor of 216,602,981 using Euclid's algorithm

Highest Common Factor of 216,602,981 is 1

Step 1: Since 602 > 216, we apply the division lemma to 602 and 216, to get

602 = 216 x 2 + 170

Step 2: Since the reminder 216 ≠ 0, we apply division lemma to 170 and 216, to get

216 = 170 x 1 + 46

Step 3: We consider the new divisor 170 and the new remainder 46, and apply the division lemma to get

170 = 46 x 3 + 32

We consider the new divisor 46 and the new remainder 32,and apply the division lemma to get

46 = 32 x 1 + 14

We consider the new divisor 32 and the new remainder 14,and apply the division lemma to get

32 = 14 x 2 + 4

We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get

14 = 4 x 3 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 216 and 602 is 2

Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(32,14) = HCF(46,32) = HCF(170,46) = HCF(216,170) = HCF(602,216) .

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

Step 1: Since 981 > 2, we apply the division lemma to 981 and 2, to get

981 = 2 x 490 + 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 981 is 1

Notice that 1 = HCF(2,1) = HCF(981,2) .
