HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 140, 400, 120 i.e. 20 the largest integer that leaves a remainder zero for all numbers.

HCF of 140, 400, 120 is 20 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 140, 400, 120 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 140, 400, 120 is 20.

HCF(140, 400, 120) = 20

HCF of 140, 400, 120 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 140, 400, 120 is 20.

Highest Common Factor of 140,400,120 using Euclid's algorithm

Highest Common Factor of 140,400,120 is 20

Step 1: Since 400 > 140, we apply the division lemma to 400 and 140, to get

400 = 140 x 2 + 120

Step 2: Since the reminder 140 ≠ 0, we apply division lemma to 120 and 140, to get

140 = 120 x 1 + 20

Step 3: We consider the new divisor 120 and the new remainder 20, and apply the division lemma to get

120 = 20 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 140 and 400 is 20

Notice that 20 = HCF(120,20) = HCF(140,120) = HCF(400,140) .


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

Step 1: Since 120 > 20, we apply the division lemma to 120 and 20, to get

120 = 20 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 20 and 120 is 20

Notice that 20 = HCF(120,20) .
