HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 544, 645, 117 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 544, 645, 117 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 544, 645, 117 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 544, 645, 117 is 1.

HCF(544, 645, 117) = 1

Highest common factor (HCF) of 544, 645, 117 is 1.

Highest Common Factor of 544,645,117 using Euclid's algorithm

Highest Common Factor of 544,645,117 is 1

Step 1: Since 645 > 544, we apply the division lemma to 645 and 544, to get

645 = 544 x 1 + 101

Step 2: Since the reminder 544 ≠ 0, we apply division lemma to 101 and 544, to get

544 = 101 x 5 + 39

Step 3: We consider the new divisor 101 and the new remainder 39, and apply the division lemma to get

101 = 39 x 2 + 23

We consider the new divisor 39 and the new remainder 23,and apply the division lemma to get

39 = 23 x 1 + 16

We consider the new divisor 23 and the new remainder 16,and apply the division lemma to get

23 = 16 x 1 + 7

We consider the new divisor 16 and the new remainder 7,and apply the division lemma to get

16 = 7 x 2 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 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 544 and 645 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(23,16) = HCF(39,23) = HCF(101,39) = HCF(544,101) = HCF(645,544) .

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

Step 1: Since 117 > 1, we apply the division lemma to 117 and 1, to get

117 = 1 x 117 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 117 is 1

Notice that 1 = HCF(117,1) .
