HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 250, 684, 654 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 250, 684, 654 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 250, 684, 654 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 250, 684, 654 is 2.

HCF(250, 684, 654) = 2

Highest common factor (HCF) of 250, 684, 654 is 2.

Highest Common Factor of 250,684,654 using Euclid's algorithm

Highest Common Factor of 250,684,654 is 2

Step 1: Since 684 > 250, we apply the division lemma to 684 and 250, to get

684 = 250 x 2 + 184

Step 2: Since the reminder 250 ≠ 0, we apply division lemma to 184 and 250, to get

250 = 184 x 1 + 66

Step 3: We consider the new divisor 184 and the new remainder 66, and apply the division lemma to get

184 = 66 x 2 + 52

We consider the new divisor 66 and the new remainder 52,and apply the division lemma to get

66 = 52 x 1 + 14

We consider the new divisor 52 and the new remainder 14,and apply the division lemma to get

52 = 14 x 3 + 10

We consider the new divisor 14 and the new remainder 10,and apply the division lemma to get

14 = 10 x 1 + 4

We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get

10 = 4 x 2 + 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 250 and 684 is 2

Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(52,14) = HCF(66,52) = HCF(184,66) = HCF(250,184) = HCF(684,250) .

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

Step 1: Since 654 > 2, we apply the division lemma to 654 and 2, to get

654 = 2 x 327 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 654 is 2

Notice that 2 = HCF(654,2) .
