HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 7640 i.e. 20 the largest integer that leaves a remainder zero for all numbers.
HCF of 980, 7640 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, 7640 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, 7640 is 20.
HCF(980, 7640) = 20
HCF of 980, 7640 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 980, 7640 is 20.
Highest Common Factor of 980,7640 is 20
Step 1: Since 7640 > 980, we apply the division lemma to 7640 and 980, to get
7640 = 980 x 7 + 780
Step 2: Since the reminder 980 ≠ 0, we apply division lemma to 780 and 980, to get
980 = 780 x 1 + 200
Step 3: We consider the new divisor 780 and the new remainder 200, and apply the division lemma to get
780 = 200 x 3 + 180
We consider the new divisor 200 and the new remainder 180,and apply the division lemma to get
200 = 180 x 1 + 20
We consider the new divisor 180 and the new remainder 20,and apply the division lemma 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 980 and 7640 is 20
Notice that 20 = HCF(180,20) = HCF(200,180) = HCF(780,200) = HCF(980,780) = HCF(7640,980) .
