HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 500, 864, 42 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 500, 864, 42 is 2 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 500, 864, 42 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 500, 864, 42 is 2.

HCF(500, 864, 42) = 2

Highest common factor (HCF) of 500, 864, 42 is 2.

Highest Common Factor of 500,864,42 using Euclid's algorithm

Highest Common Factor of 500,864,42 is 2

Step 1: Since 864 > 500, we apply the division lemma to 864 and 500, to get

864 = 500 x 1 + 364

Step 2: Since the reminder 500 ≠ 0, we apply division lemma to 364 and 500, to get

500 = 364 x 1 + 136

Step 3: We consider the new divisor 364 and the new remainder 136, and apply the division lemma to get

364 = 136 x 2 + 92

We consider the new divisor 136 and the new remainder 92,and apply the division lemma to get

136 = 92 x 1 + 44

We consider the new divisor 92 and the new remainder 44,and apply the division lemma to get

92 = 44 x 2 + 4

We consider the new divisor 44 and the new remainder 4,and apply the division lemma to get

44 = 4 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 500 and 864 is 4

Notice that 4 = HCF(44,4) = HCF(92,44) = HCF(136,92) = HCF(364,136) = HCF(500,364) = HCF(864,500) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 42 > 4, we apply the division lemma to 42 and 4, to get

42 = 4 x 10 + 2

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 42 is 2

Notice that 2 = HCF(4,2) = HCF(42,4) .
