HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 862, 481 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 862, 481 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 862, 481 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 862, 481 is 1.

HCF(862, 481) = 1

Highest common factor (HCF) of 862, 481 is 1.

Highest Common Factor of 862,481 using Euclid's algorithm

Highest Common Factor of 862,481 is 1

Step 1: Since 862 > 481, we apply the division lemma to 862 and 481, to get

862 = 481 x 1 + 381

Step 2: Since the reminder 481 ≠ 0, we apply division lemma to 381 and 481, to get

481 = 381 x 1 + 100

Step 3: We consider the new divisor 381 and the new remainder 100, and apply the division lemma to get

381 = 100 x 3 + 81

We consider the new divisor 100 and the new remainder 81,and apply the division lemma to get

100 = 81 x 1 + 19

We consider the new divisor 81 and the new remainder 19,and apply the division lemma to get

81 = 19 x 4 + 5

We consider the new divisor 19 and the new remainder 5,and apply the division lemma to get

19 = 5 x 3 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 862 and 481 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(19,5) = HCF(81,19) = HCF(100,81) = HCF(381,100) = HCF(481,381) = HCF(862,481) .
