HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7720, 7869 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 7720, 7869 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 7720, 7869 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 7720, 7869 is 1.

HCF(7720, 7869) = 1

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

HCF of:

Highest common factor (HCF) of 7720, 7869 is 1.

Highest Common Factor of 7720,7869 using Euclid's algorithm

Highest Common Factor of 7720,7869 is 1

Step 1: Since 7869 > 7720, we apply the division lemma to 7869 and 7720, to get

7869 = 7720 x 1 + 149

Step 2: Since the reminder 7720 ≠ 0, we apply division lemma to 149 and 7720, to get

7720 = 149 x 51 + 121

Step 3: We consider the new divisor 149 and the new remainder 121, and apply the division lemma to get

149 = 121 x 1 + 28

We consider the new divisor 121 and the new remainder 28,and apply the division lemma to get

121 = 28 x 4 + 9

We consider the new divisor 28 and the new remainder 9,and apply the division lemma to get

28 = 9 x 3 + 1

We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7720 and 7869 is 1

Notice that 1 = HCF(9,1) = HCF(28,9) = HCF(121,28) = HCF(149,121) = HCF(7720,149) = HCF(7869,7720) .
