HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 125, 415, 120 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 125, 415, 120 is 5 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 125, 415, 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 125, 415, 120 is 5.

HCF(125, 415, 120) = 5

## HCF of 125, 415, 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 125, 415, 120 is 5. ### Highest Common Factor of 125,415,120 is 5

Step 1: Since 415 > 125, we apply the division lemma to 415 and 125, to get

415 = 125 x 3 + 40

Step 2: Since the reminder 125 ≠ 0, we apply division lemma to 40 and 125, to get

125 = 40 x 3 + 5

Step 3: We consider the new divisor 40 and the new remainder 5, and apply the division lemma to get

40 = 5 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 125 and 415 is 5

Notice that 5 = HCF(40,5) = HCF(125,40) = HCF(415,125) .

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

Step 1: Since 120 > 5, we apply the division lemma to 120 and 5, to get

120 = 5 x 24 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 120 is 5

Notice that 5 = HCF(120,5) .
