HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 309, 654, 880 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 309, 654, 880 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 309, 654, 880 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 309, 654, 880 is 1.

HCF(309, 654, 880) = 1

Highest common factor (HCF) of 309, 654, 880 is 1.

Highest Common Factor of 309,654,880 using Euclid's algorithm

Highest Common Factor of 309,654,880 is 1

Step 1: Since 654 > 309, we apply the division lemma to 654 and 309, to get

654 = 309 x 2 + 36

Step 2: Since the reminder 309 ≠ 0, we apply division lemma to 36 and 309, to get

309 = 36 x 8 + 21

Step 3: We consider the new divisor 36 and the new remainder 21, and apply the division lemma to get

36 = 21 x 1 + 15

We consider the new divisor 21 and the new remainder 15,and apply the division lemma to get

21 = 15 x 1 + 6

We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get

15 = 6 x 2 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 309 and 654 is 3

Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(21,15) = HCF(36,21) = HCF(309,36) = HCF(654,309) .

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

Step 1: Since 880 > 3, we apply the division lemma to 880 and 3, to get

880 = 3 x 293 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 880 is 1

Notice that 1 = HCF(3,1) = HCF(880,3) .
