HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 162, 786 i.e. 6 the largest integer that leaves a remainder zero for all numbers.

HCF of 162, 786 is 6 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 162, 786 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 162, 786 is 6.

HCF(162, 786) = 6

HCF of 162, 786 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 162, 786 is 6.

Highest Common Factor of 162,786 using Euclid's algorithm

Highest Common Factor of 162,786 is 6

Step 1: Since 786 > 162, we apply the division lemma to 786 and 162, to get

786 = 162 x 4 + 138

Step 2: Since the reminder 162 ≠ 0, we apply division lemma to 138 and 162, to get

162 = 138 x 1 + 24

Step 3: We consider the new divisor 138 and the new remainder 24, and apply the division lemma to get

138 = 24 x 5 + 18

We consider the new divisor 24 and the new remainder 18,and apply the division lemma to get

24 = 18 x 1 + 6

We consider the new divisor 18 and the new remainder 6,and apply the division lemma to get

18 = 6 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 162 and 786 is 6

Notice that 6 = HCF(18,6) = HCF(24,18) = HCF(138,24) = HCF(162,138) = HCF(786,162) .
