HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 981, 411, 572 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 981, 411, 572 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 981, 411, 572 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 981, 411, 572 is 1.

HCF(981, 411, 572) = 1

Highest common factor (HCF) of 981, 411, 572 is 1.

Highest Common Factor of 981,411,572 using Euclid's algorithm

Highest Common Factor of 981,411,572 is 1

Step 1: Since 981 > 411, we apply the division lemma to 981 and 411, to get

981 = 411 x 2 + 159

Step 2: Since the reminder 411 ≠ 0, we apply division lemma to 159 and 411, to get

411 = 159 x 2 + 93

Step 3: We consider the new divisor 159 and the new remainder 93, and apply the division lemma to get

159 = 93 x 1 + 66

We consider the new divisor 93 and the new remainder 66,and apply the division lemma to get

93 = 66 x 1 + 27

We consider the new divisor 66 and the new remainder 27,and apply the division lemma to get

66 = 27 x 2 + 12

We consider the new divisor 27 and the new remainder 12,and apply the division lemma to get

27 = 12 x 2 + 3

We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get

12 = 3 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 981 and 411 is 3

Notice that 3 = HCF(12,3) = HCF(27,12) = HCF(66,27) = HCF(93,66) = HCF(159,93) = HCF(411,159) = HCF(981,411) .

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

Step 1: Since 572 > 3, we apply the division lemma to 572 and 3, to get

572 = 3 x 190 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: 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 3 and 572 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(572,3) .
