HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 654, 717, 754 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 654, 717, 754 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 654, 717, 754 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 654, 717, 754 is 1.

HCF(654, 717, 754) = 1

Highest common factor (HCF) of 654, 717, 754 is 1.

Highest Common Factor of 654,717,754 using Euclid's algorithm

Highest Common Factor of 654,717,754 is 1

Step 1: Since 717 > 654, we apply the division lemma to 717 and 654, to get

717 = 654 x 1 + 63

Step 2: Since the reminder 654 ≠ 0, we apply division lemma to 63 and 654, to get

654 = 63 x 10 + 24

Step 3: We consider the new divisor 63 and the new remainder 24, and apply the division lemma to get

63 = 24 x 2 + 15

We consider the new divisor 24 and the new remainder 15,and apply the division lemma to get

24 = 15 x 1 + 9

We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get

15 = 9 x 1 + 6

We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get

9 = 6 x 1 + 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 654 and 717 is 3

Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(24,15) = HCF(63,24) = HCF(654,63) = HCF(717,654) .

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

Step 1: Since 754 > 3, we apply the division lemma to 754 and 3, to get

754 = 3 x 251 + 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 754 is 1

Notice that 1 = HCF(3,1) = HCF(754,3) .
