HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 660 i.e. 20 the largest integer that leaves a remainder zero for all numbers.

HCF of 980, 660 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 980, 660 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 980, 660 is 20.

HCF(980, 660) = 20

Highest common factor (HCF) of 980, 660 is 20.

Highest Common Factor of 980,660 using Euclid's algorithm

Highest Common Factor of 980,660 is 20

Step 1: Since 980 > 660, we apply the division lemma to 980 and 660, to get

980 = 660 x 1 + 320

Step 2: Since the reminder 660 ≠ 0, we apply division lemma to 320 and 660, to get

660 = 320 x 2 + 20

Step 3: We consider the new divisor 320 and the new remainder 20, and apply the division lemma to get

320 = 20 x 16 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 980 and 660 is 20

Notice that 20 = HCF(320,20) = HCF(660,320) = HCF(980,660) .
