HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 151, 228, 240 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 151, 228, 240 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 151, 228, 240 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 151, 228, 240 is 1.

HCF(151, 228, 240) = 1

Highest common factor (HCF) of 151, 228, 240 is 1.

Highest Common Factor of 151,228,240 using Euclid's algorithm

Highest Common Factor of 151,228,240 is 1

Step 1: Since 228 > 151, we apply the division lemma to 228 and 151, to get

228 = 151 x 1 + 77

Step 2: Since the reminder 151 ≠ 0, we apply division lemma to 77 and 151, to get

151 = 77 x 1 + 74

Step 3: We consider the new divisor 77 and the new remainder 74, and apply the division lemma to get

77 = 74 x 1 + 3

We consider the new divisor 74 and the new remainder 3,and apply the division lemma to get

74 = 3 x 24 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 151 and 228 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(74,3) = HCF(77,74) = HCF(151,77) = HCF(228,151) .

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

Step 1: Since 240 > 1, we apply the division lemma to 240 and 1, to get

240 = 1 x 240 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 240 is 1

Notice that 1 = HCF(240,1) .
