HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 4731, 7986 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 4731, 7986 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 4731, 7986 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 4731, 7986 is 3.
HCF(4731, 7986) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 4731, 7986 is 3.
Step 1: Since 7986 > 4731, we apply the division lemma to 7986 and 4731, to get
7986 = 4731 x 1 + 3255
Step 2: Since the reminder 4731 ≠ 0, we apply division lemma to 3255 and 4731, to get
4731 = 3255 x 1 + 1476
Step 3: We consider the new divisor 3255 and the new remainder 1476, and apply the division lemma to get
3255 = 1476 x 2 + 303
We consider the new divisor 1476 and the new remainder 303,and apply the division lemma to get
1476 = 303 x 4 + 264
We consider the new divisor 303 and the new remainder 264,and apply the division lemma to get
303 = 264 x 1 + 39
We consider the new divisor 264 and the new remainder 39,and apply the division lemma to get
264 = 39 x 6 + 30
We consider the new divisor 39 and the new remainder 30,and apply the division lemma to get
39 = 30 x 1 + 9
We consider the new divisor 30 and the new remainder 9,and apply the division lemma to get
30 = 9 x 3 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 4731 and 7986 is 3
Notice that 3 = HCF(9,3) = HCF(30,9) = HCF(39,30) = HCF(264,39) = HCF(303,264) = HCF(1476,303) = HCF(3255,1476) = HCF(4731,3255) = HCF(7986,4731) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
