HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 4047, 2658 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 4047, 2658 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 4047, 2658 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 4047, 2658 is 3.
HCF(4047, 2658) = 3
HCF of 4047, 2658 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 4047, 2658 is 3.
Highest Common Factor of 4047,2658 is 3
Step 1: Since 4047 > 2658, we apply the division lemma to 4047 and 2658, to get
4047 = 2658 x 1 + 1389
Step 2: Since the reminder 2658 ≠ 0, we apply division lemma to 1389 and 2658, to get
2658 = 1389 x 1 + 1269
Step 3: We consider the new divisor 1389 and the new remainder 1269, and apply the division lemma to get
1389 = 1269 x 1 + 120
We consider the new divisor 1269 and the new remainder 120,and apply the division lemma to get
1269 = 120 x 10 + 69
We consider the new divisor 120 and the new remainder 69,and apply the division lemma to get
120 = 69 x 1 + 51
We consider the new divisor 69 and the new remainder 51,and apply the division lemma to get
69 = 51 x 1 + 18
We consider the new divisor 51 and the new remainder 18,and apply the division lemma to get
51 = 18 x 2 + 15
We consider the new divisor 18 and the new remainder 15,and apply the division lemma to get
18 = 15 x 1 + 3
We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 4047 and 2658 is 3
Notice that 3 = HCF(15,3) = HCF(18,15) = HCF(51,18) = HCF(69,51) = HCF(120,69) = HCF(1269,120) = HCF(1389,1269) = HCF(2658,1389) = HCF(4047,2658) .
