HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 681, 381, 952 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 681, 381, 952 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 681, 381, 952 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 681, 381, 952 is 1.

HCF(681, 381, 952) = 1

Highest common factor (HCF) of 681, 381, 952 is 1.

Highest Common Factor of 681,381,952 using Euclid's algorithm

Highest Common Factor of 681,381,952 is 1

Step 1: Since 681 > 381, we apply the division lemma to 681 and 381, to get

681 = 381 x 1 + 300

Step 2: Since the reminder 381 ≠ 0, we apply division lemma to 300 and 381, to get

381 = 300 x 1 + 81

Step 3: We consider the new divisor 300 and the new remainder 81, and apply the division lemma to get

300 = 81 x 3 + 57

We consider the new divisor 81 and the new remainder 57,and apply the division lemma to get

81 = 57 x 1 + 24

We consider the new divisor 57 and the new remainder 24,and apply the division lemma to get

57 = 24 x 2 + 9

We consider the new divisor 24 and the new remainder 9,and apply the division lemma to get

24 = 9 x 2 + 6

We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get

9 = 6 x 1 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 681 and 381 is 3

Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(24,9) = HCF(57,24) = HCF(81,57) = HCF(300,81) = HCF(381,300) = HCF(681,381) .

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

Step 1: Since 952 > 3, we apply the division lemma to 952 and 3, to get

952 = 3 x 317 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 952 is 1

Notice that 1 = HCF(3,1) = HCF(952,3) .
