HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 582, 862, 645 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 582, 862, 645 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 582, 862, 645 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 582, 862, 645 is 1.

HCF(582, 862, 645) = 1

Highest common factor (HCF) of 582, 862, 645 is 1.

Highest Common Factor of 582,862,645 using Euclid's algorithm

Highest Common Factor of 582,862,645 is 1

Step 1: Since 862 > 582, we apply the division lemma to 862 and 582, to get

862 = 582 x 1 + 280

Step 2: Since the reminder 582 ≠ 0, we apply division lemma to 280 and 582, to get

582 = 280 x 2 + 22

Step 3: We consider the new divisor 280 and the new remainder 22, and apply the division lemma to get

280 = 22 x 12 + 16

We consider the new divisor 22 and the new remainder 16,and apply the division lemma to get

22 = 16 x 1 + 6

We consider the new divisor 16 and the new remainder 6,and apply the division lemma to get

16 = 6 x 2 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma 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 582 and 862 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(22,16) = HCF(280,22) = HCF(582,280) = HCF(862,582) .

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

Step 1: Since 645 > 2, we apply the division lemma to 645 and 2, to get

645 = 2 x 322 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 645 is 1

Notice that 1 = HCF(2,1) = HCF(645,2) .
