HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 137, 254, 140 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 137, 254, 140 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 137, 254, 140 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 137, 254, 140 is 1.

HCF(137, 254, 140) = 1

HCF of 137, 254, 140 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 137, 254, 140 is 1.

Highest Common Factor of 137,254,140 using Euclid's algorithm

Highest Common Factor of 137,254,140 is 1

Step 1: Since 254 > 137, we apply the division lemma to 254 and 137, to get

254 = 137 x 1 + 117

Step 2: Since the reminder 137 ≠ 0, we apply division lemma to 117 and 137, to get

137 = 117 x 1 + 20

Step 3: We consider the new divisor 117 and the new remainder 20, and apply the division lemma to get

117 = 20 x 5 + 17

We consider the new divisor 20 and the new remainder 17,and apply the division lemma to get

20 = 17 x 1 + 3

We consider the new divisor 17 and the new remainder 3,and apply the division lemma to get

17 = 3 x 5 + 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 137 and 254 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(20,17) = HCF(117,20) = HCF(137,117) = HCF(254,137) .

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

Step 1: Since 140 > 1, we apply the division lemma to 140 and 1, to get

140 = 1 x 140 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 140 is 1

Notice that 1 = HCF(140,1) .
