HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 640, 862, 176 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 640, 862, 176 is 2 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 640, 862, 176 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 640, 862, 176 is 2.

HCF(640, 862, 176) = 2

Highest common factor (HCF) of 640, 862, 176 is 2.

Highest Common Factor of 640,862,176 using Euclid's algorithm

Highest Common Factor of 640,862,176 is 2

Step 1: Since 862 > 640, we apply the division lemma to 862 and 640, to get

862 = 640 x 1 + 222

Step 2: Since the reminder 640 ≠ 0, we apply division lemma to 222 and 640, to get

640 = 222 x 2 + 196

Step 3: We consider the new divisor 222 and the new remainder 196, and apply the division lemma to get

222 = 196 x 1 + 26

We consider the new divisor 196 and the new remainder 26,and apply the division lemma to get

196 = 26 x 7 + 14

We consider the new divisor 26 and the new remainder 14,and apply the division lemma to get

26 = 14 x 1 + 12

We consider the new divisor 14 and the new remainder 12,and apply the division lemma to get

14 = 12 x 1 + 2

We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get

12 = 2 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 640 and 862 is 2

Notice that 2 = HCF(12,2) = HCF(14,12) = HCF(26,14) = HCF(196,26) = HCF(222,196) = HCF(640,222) = HCF(862,640) .

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

Step 1: Since 176 > 2, we apply the division lemma to 176 and 2, to get

176 = 2 x 88 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 176 is 2

Notice that 2 = HCF(176,2) .
