HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 80, 40, 146 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 80, 40, 146 is 2 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 80, 40, 146 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 80, 40, 146 is 2.

HCF(80, 40, 146) = 2

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

HCF of:

Highest common factor (HCF) of 80, 40, 146 is 2.

Highest Common Factor of 80,40,146 using Euclid's algorithm

Highest Common Factor of 80,40,146 is 2

Step 1: Since 80 > 40, we apply the division lemma to 80 and 40, to get

80 = 40 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 40, the HCF of 80 and 40 is 40

Notice that 40 = HCF(80,40) .


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

Step 1: Since 146 > 40, we apply the division lemma to 146 and 40, to get

146 = 40 x 3 + 26

Step 2: Since the reminder 40 ≠ 0, we apply division lemma to 26 and 40, to get

40 = 26 x 1 + 14

Step 3: We consider the new divisor 26 and the new remainder 14, and apply the division lemma to get

26 = 14 x 1 + 12

We consider the new divisor 14 and the new remainder 12,and apply the division lemma to get

14 = 12 x 1 + 2

We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get

12 = 2 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 40 and 146 is 2

Notice that 2 = HCF(12,2) = HCF(14,12) = HCF(26,14) = HCF(40,26) = HCF(146,40) .
