HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 247, 855 i.e. 19 the largest integer that leaves a remainder zero for all numbers.

HCF of 247, 855 is 19 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 247, 855 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 247, 855 is 19.

HCF(247, 855) = 19

Highest common factor (HCF) of 247, 855 is 19.

Highest Common Factor of 247,855 using Euclid's algorithm

Highest Common Factor of 247,855 is 19

Step 1: Since 855 > 247, we apply the division lemma to 855 and 247, to get

855 = 247 x 3 + 114

Step 2: Since the reminder 247 ≠ 0, we apply division lemma to 114 and 247, to get

247 = 114 x 2 + 19

Step 3: We consider the new divisor 114 and the new remainder 19, and apply the division lemma to get

114 = 19 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 247 and 855 is 19

Notice that 19 = HCF(114,19) = HCF(247,114) = HCF(855,247) .
