HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 986, 2020 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 986, 2020 is 2 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 986, 2020 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 986, 2020 is 2.
HCF(986, 2020) = 2
HCF of 986, 2020 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 986, 2020 is 2.
Highest Common Factor of 986,2020 is 2
Step 1: Since 2020 > 986, we apply the division lemma to 2020 and 986, to get
2020 = 986 x 2 + 48
Step 2: Since the reminder 986 ≠ 0, we apply division lemma to 48 and 986, to get
986 = 48 x 20 + 26
Step 3: We consider the new divisor 48 and the new remainder 26, and apply the division lemma to get
48 = 26 x 1 + 22
We consider the new divisor 26 and the new remainder 22,and apply the division lemma to get
26 = 22 x 1 + 4
We consider the new divisor 22 and the new remainder 4,and apply the division lemma to get
22 = 4 x 5 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 986 and 2020 is 2
Notice that 2 = HCF(4,2) = HCF(22,4) = HCF(26,22) = HCF(48,26) = HCF(986,48) = HCF(2020,986) .
