HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 857, 235, 662 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 857, 235, 662 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 857, 235, 662 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 857, 235, 662 is 1.

HCF(857, 235, 662) = 1

Highest common factor (HCF) of 857, 235, 662 is 1.

Highest Common Factor of 857,235,662 using Euclid's algorithm

Highest Common Factor of 857,235,662 is 1

Step 1: Since 857 > 235, we apply the division lemma to 857 and 235, to get

857 = 235 x 3 + 152

Step 2: Since the reminder 235 ≠ 0, we apply division lemma to 152 and 235, to get

235 = 152 x 1 + 83

Step 3: We consider the new divisor 152 and the new remainder 83, and apply the division lemma to get

152 = 83 x 1 + 69

We consider the new divisor 83 and the new remainder 69,and apply the division lemma to get

83 = 69 x 1 + 14

We consider the new divisor 69 and the new remainder 14,and apply the division lemma to get

69 = 14 x 4 + 13

We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get

14 = 13 x 1 + 1

We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 857 and 235 is 1

Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(69,14) = HCF(83,69) = HCF(152,83) = HCF(235,152) = HCF(857,235) .

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

Step 1: Since 662 > 1, we apply the division lemma to 662 and 1, to get

662 = 1 x 662 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 662 is 1

Notice that 1 = HCF(662,1) .
