HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 920, 180 i.e. 20 the largest integer that leaves a remainder zero for all numbers.

HCF of 920, 180 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 920, 180 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 920, 180 is 20.

HCF(920, 180) = 20

HCF of 920, 180 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 920, 180 is 20.

Highest Common Factor of 920,180 using Euclid's algorithm

Highest Common Factor of 920,180 is 20

Step 1: Since 920 > 180, we apply the division lemma to 920 and 180, to get

920 = 180 x 5 + 20

Step 2: Since the reminder 180 ≠ 0, we apply division lemma to 20 and 180, to get

180 = 20 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 920 and 180 is 20

Notice that 20 = HCF(180,20) = HCF(920,180) .
