HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 544, 659, 745 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 544, 659, 745 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, 659, 745 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, 659, 745 is 1.

HCF(544, 659, 745) = 1

Highest common factor (HCF) of 544, 659, 745 is 1.

Highest Common Factor of 544,659,745 using Euclid's algorithm

Highest Common Factor of 544,659,745 is 1

Step 1: Since 659 > 544, we apply the division lemma to 659 and 544, to get

659 = 544 x 1 + 115

Step 2: Since the reminder 544 ≠ 0, we apply division lemma to 115 and 544, to get

544 = 115 x 4 + 84

Step 3: We consider the new divisor 115 and the new remainder 84, and apply the division lemma to get

115 = 84 x 1 + 31

We consider the new divisor 84 and the new remainder 31,and apply the division lemma to get

84 = 31 x 2 + 22

We consider the new divisor 31 and the new remainder 22,and apply the division lemma to get

31 = 22 x 1 + 9

We consider the new divisor 22 and the new remainder 9,and apply the division lemma to get

22 = 9 x 2 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 544 and 659 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(22,9) = HCF(31,22) = HCF(84,31) = HCF(115,84) = HCF(544,115) = HCF(659,544) .

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

Step 1: Since 745 > 1, we apply the division lemma to 745 and 1, to get

745 = 1 x 745 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 745 is 1

Notice that 1 = HCF(745,1) .
