HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1983, 4215 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 1983, 4215 is 3 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 1983, 4215 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 1983, 4215 is 3.
HCF(1983, 4215) = 3
HCF of 1983, 4215 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1983, 4215 is 3.
Highest Common Factor of 1983,4215 is 3
Step 1: Since 4215 > 1983, we apply the division lemma to 4215 and 1983, to get
4215 = 1983 x 2 + 249
Step 2: Since the reminder 1983 ≠ 0, we apply division lemma to 249 and 1983, to get
1983 = 249 x 7 + 240
Step 3: We consider the new divisor 249 and the new remainder 240, and apply the division lemma to get
249 = 240 x 1 + 9
We consider the new divisor 240 and the new remainder 9,and apply the division lemma to get
240 = 9 x 26 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 1983 and 4215 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(240,9) = HCF(249,240) = HCF(1983,249) = HCF(4215,1983) .
