HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 784, 864 i.e. 16 the largest integer that leaves a remainder zero for all numbers.

HCF of 784, 864 is 16 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 784, 864 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 784, 864 is 16.

HCF(784, 864) = 16

HCF of 784, 864 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 784, 864 is 16.

Highest Common Factor of 784,864 using Euclid's algorithm

Highest Common Factor of 784,864 is 16

Step 1: Since 864 > 784, we apply the division lemma to 864 and 784, to get

864 = 784 x 1 + 80

Step 2: Since the reminder 784 ≠ 0, we apply division lemma to 80 and 784, to get

784 = 80 x 9 + 64

Step 3: We consider the new divisor 80 and the new remainder 64, and apply the division lemma to get

80 = 64 x 1 + 16

We consider the new divisor 64 and the new remainder 16, and apply the division lemma to get

64 = 16 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 16, the HCF of 784 and 864 is 16

Notice that 16 = HCF(64,16) = HCF(80,64) = HCF(784,80) = HCF(864,784) .
