HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 84, 157, 471, 461 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 84, 157, 471, 461 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 84, 157, 471, 461 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 84, 157, 471, 461 is 1.

HCF(84, 157, 471, 461) = 1

Highest Common Factor of 84,157,471,461 using Euclid's algorithm

Highest Common Factor of 84,157,471,461 is 1

Step 1: Since 157 > 84, we apply the division lemma to 157 and 84, to get

157 = 84 x 1 + 73

Step 2: Since the reminder 84 ≠ 0, we apply division lemma to 73 and 84, to get

84 = 73 x 1 + 11

Step 3: We consider the new divisor 73 and the new remainder 11, and apply the division lemma to get

73 = 11 x 6 + 7

We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get

11 = 7 x 1 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 84 and 157 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(73,11) = HCF(84,73) = HCF(157,84) .

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

Step 1: Since 471 > 1, we apply the division lemma to 471 and 1, to get

471 = 1 x 471 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 471 is 1

Notice that 1 = HCF(471,1) .

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

Step 1: Since 461 > 1, we apply the division lemma to 461 and 1, to get

461 = 1 x 461 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 461 is 1

Notice that 1 = HCF(461,1) .
