HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 284, 1215 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 284, 1215 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 284, 1215 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 284, 1215 is 1.

HCF(284, 1215) = 1

Highest common factor (HCF) of 284, 1215 is 1.

Highest Common Factor of 284,1215 using Euclid's algorithm

Highest Common Factor of 284,1215 is 1

Step 1: Since 1215 > 284, we apply the division lemma to 1215 and 284, to get

1215 = 284 x 4 + 79

Step 2: Since the reminder 284 ≠ 0, we apply division lemma to 79 and 284, to get

284 = 79 x 3 + 47

Step 3: We consider the new divisor 79 and the new remainder 47, and apply the division lemma to get

79 = 47 x 1 + 32

We consider the new divisor 47 and the new remainder 32,and apply the division lemma to get

47 = 32 x 1 + 15

We consider the new divisor 32 and the new remainder 15,and apply the division lemma to get

32 = 15 x 2 + 2

We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get

15 = 2 x 7 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 284 and 1215 is 1

Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(32,15) = HCF(47,32) = HCF(79,47) = HCF(284,79) = HCF(1215,284) .
