# Highest Common Factor of 126, 18, 684 using Euclid's algorithm

HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 126, 18, 684 i.e. 18 the largest integer that leaves a remainder zero for all numbers.

HCF of 126, 18, 684 is 18 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 126, 18, 684 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 126, 18, 684 is 18.

HCF(126, 18, 684) = 18

## HCF of 126, 18, 684 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 126, 18, 684 is 18.

### Highest Common Factor of 126,18,684 using Euclid's algorithm

Step 1: Since 126 > 18, we apply the division lemma to 126 and 18, to get

126 = 18 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 126 and 18 is 18

Notice that 18 = HCF(126,18) .

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

Step 1: Since 684 > 18, we apply the division lemma to 684 and 18, to get

684 = 18 x 38 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 18 and 684 is 18

Notice that 18 = HCF(684,18) .
