HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 384, 583, 956, 645 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 384, 583, 956, 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 384, 583, 956, 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 384, 583, 956, 645 is 1.

HCF(384, 583, 956, 645) = 1

Highest Common Factor of 384,583,956,645 using Euclid's algorithm

Highest Common Factor of 384,583,956,645 is 1

Step 1: Since 583 > 384, we apply the division lemma to 583 and 384, to get

583 = 384 x 1 + 199

Step 2: Since the reminder 384 ≠ 0, we apply division lemma to 199 and 384, to get

384 = 199 x 1 + 185

Step 3: We consider the new divisor 199 and the new remainder 185, and apply the division lemma to get

199 = 185 x 1 + 14

We consider the new divisor 185 and the new remainder 14,and apply the division lemma to get

185 = 14 x 13 + 3

We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get

14 = 3 x 4 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 384 and 583 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(185,14) = HCF(199,185) = HCF(384,199) = HCF(583,384) .

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

Step 1: Since 956 > 1, we apply the division lemma to 956 and 1, to get

956 = 1 x 956 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 956 is 1

Notice that 1 = HCF(956,1) .

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

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

645 = 1 x 645 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 645 is 1

Notice that 1 = HCF(645,1) .
