HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 615, 745, 502, 43 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 615, 745, 502, 43 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 615, 745, 502, 43 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 615, 745, 502, 43 is 1.

HCF(615, 745, 502, 43) = 1

Highest common factor (HCF) of 615, 745, 502, 43 is 1.

Highest Common Factor of 615,745,502,43 using Euclid's algorithm

Highest Common Factor of 615,745,502,43 is 1

Step 1: Since 745 > 615, we apply the division lemma to 745 and 615, to get

745 = 615 x 1 + 130

Step 2: Since the reminder 615 ≠ 0, we apply division lemma to 130 and 615, to get

615 = 130 x 4 + 95

Step 3: We consider the new divisor 130 and the new remainder 95, and apply the division lemma to get

130 = 95 x 1 + 35

We consider the new divisor 95 and the new remainder 35,and apply the division lemma to get

95 = 35 x 2 + 25

We consider the new divisor 35 and the new remainder 25,and apply the division lemma to get

35 = 25 x 1 + 10

We consider the new divisor 25 and the new remainder 10,and apply the division lemma to get

25 = 10 x 2 + 5

We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get

10 = 5 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 615 and 745 is 5

Notice that 5 = HCF(10,5) = HCF(25,10) = HCF(35,25) = HCF(95,35) = HCF(130,95) = HCF(615,130) = HCF(745,615) .


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

Step 1: Since 502 > 5, we apply the division lemma to 502 and 5, to get

502 = 5 x 100 + 2

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get

5 = 2 x 2 + 1

Step 3: 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 5 and 502 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(502,5) .


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

Step 1: Since 43 > 1, we apply the division lemma to 43 and 1, to get

43 = 1 x 43 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 43 is 1

Notice that 1 = HCF(43,1) .
