HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 87, 348, 857 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 87, 348, 857 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 87, 348, 857 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 87, 348, 857 is 1.

HCF(87, 348, 857) = 1

Highest common factor (HCF) of 87, 348, 857 is 1.

Highest Common Factor of 87,348,857 using Euclid's algorithm

Highest Common Factor of 87,348,857 is 1

Step 1: Since 348 > 87, we apply the division lemma to 348 and 87, to get

348 = 87 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 87, the HCF of 87 and 348 is 87

Notice that 87 = HCF(348,87) .

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

Step 1: Since 857 > 87, we apply the division lemma to 857 and 87, to get

857 = 87 x 9 + 74

Step 2: Since the reminder 87 ≠ 0, we apply division lemma to 74 and 87, to get

87 = 74 x 1 + 13

Step 3: We consider the new divisor 74 and the new remainder 13, and apply the division lemma to get

74 = 13 x 5 + 9

We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get

13 = 9 x 1 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 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 87 and 857 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(74,13) = HCF(87,74) = HCF(857,87) .
