HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 400, 163, 851 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 400, 163, 851 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 400, 163, 851 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 400, 163, 851 is 1.

HCF(400, 163, 851) = 1

HCF of 400, 163, 851 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 400, 163, 851 is 1.

Highest Common Factor of 400,163,851 using Euclid's algorithm

Highest Common Factor of 400,163,851 is 1

Step 1: Since 400 > 163, we apply the division lemma to 400 and 163, to get

400 = 163 x 2 + 74

Step 2: Since the reminder 163 ≠ 0, we apply division lemma to 74 and 163, to get

163 = 74 x 2 + 15

Step 3: We consider the new divisor 74 and the new remainder 15, and apply the division lemma to get

74 = 15 x 4 + 14

We consider the new divisor 15 and the new remainder 14,and apply the division lemma to get

15 = 14 x 1 + 1

We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get

14 = 1 x 14 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 400 and 163 is 1

Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(74,15) = HCF(163,74) = HCF(400,163) .


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

Step 1: Since 851 > 1, we apply the division lemma to 851 and 1, to get

851 = 1 x 851 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 851 is 1

Notice that 1 = HCF(851,1) .
