HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 979, 1818 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 979, 1818 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 979, 1818 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 979, 1818 is 1.

HCF(979, 1818) = 1

HCF of 979, 1818 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 979, 1818 is 1.

Highest Common Factor of 979,1818 using Euclid's algorithm

Highest Common Factor of 979,1818 is 1

Step 1: Since 1818 > 979, we apply the division lemma to 1818 and 979, to get

1818 = 979 x 1 + 839

Step 2: Since the reminder 979 ≠ 0, we apply division lemma to 839 and 979, to get

979 = 839 x 1 + 140

Step 3: We consider the new divisor 839 and the new remainder 140, and apply the division lemma to get

839 = 140 x 5 + 139

We consider the new divisor 140 and the new remainder 139,and apply the division lemma to get

140 = 139 x 1 + 1

We consider the new divisor 139 and the new remainder 1,and apply the division lemma to get

139 = 1 x 139 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 979 and 1818 is 1

Notice that 1 = HCF(139,1) = HCF(140,139) = HCF(839,140) = HCF(979,839) = HCF(1818,979) .
