HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 43, 28, 151, 103 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 43, 28, 151, 103 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 43, 28, 151, 103 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 43, 28, 151, 103 is 1.

HCF(43, 28, 151, 103) = 1

Highest common factor (HCF) of 43, 28, 151, 103 is 1.

Highest Common Factor of 43,28,151,103 using Euclid's algorithm

Highest Common Factor of 43,28,151,103 is 1

Step 1: Since 43 > 28, we apply the division lemma to 43 and 28, to get

43 = 28 x 1 + 15

Step 2: Since the reminder 28 ≠ 0, we apply division lemma to 15 and 28, to get

28 = 15 x 1 + 13

Step 3: We consider the new divisor 15 and the new remainder 13, and apply the division lemma to get

15 = 13 x 1 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 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 43 and 28 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(28,15) = HCF(43,28) .


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

Step 1: Since 151 > 1, we apply the division lemma to 151 and 1, to get

151 = 1 x 151 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 151 is 1

Notice that 1 = HCF(151,1) .


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

Step 1: Since 103 > 1, we apply the division lemma to 103 and 1, to get

103 = 1 x 103 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 103 is 1

Notice that 1 = HCF(103,1) .
