HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 120, 280 i.e. 40 the largest integer that leaves a remainder zero for all numbers.

HCF of 120, 280 is 40 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 120, 280 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 120, 280 is 40.

HCF(120, 280) = 40

HCF of 120, 280 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 120, 280 is 40.

Highest Common Factor of 120,280 using Euclid's algorithm

Highest Common Factor of 120,280 is 40

Step 1: Since 280 > 120, we apply the division lemma to 280 and 120, to get

280 = 120 x 2 + 40

Step 2: Since the reminder 120 ≠ 0, we apply division lemma to 40 and 120, to get

120 = 40 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 40, the HCF of 120 and 280 is 40

Notice that 40 = HCF(120,40) = HCF(280,120) .
