HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 291, 6642 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 291, 6642 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 291, 6642 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 291, 6642 is 3.
HCF(291, 6642) = 3
HCF of 291, 6642 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 291, 6642 is 3.
Highest Common Factor of 291,6642 is 3
Step 1: Since 6642 > 291, we apply the division lemma to 6642 and 291, to get
6642 = 291 x 22 + 240
Step 2: Since the reminder 291 ≠ 0, we apply division lemma to 240 and 291, to get
291 = 240 x 1 + 51
Step 3: We consider the new divisor 240 and the new remainder 51, and apply the division lemma to get
240 = 51 x 4 + 36
We consider the new divisor 51 and the new remainder 36,and apply the division lemma to get
51 = 36 x 1 + 15
We consider the new divisor 36 and the new remainder 15,and apply the division lemma to get
36 = 15 x 2 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 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 291 and 6642 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(36,15) = HCF(51,36) = HCF(240,51) = HCF(291,240) = HCF(6642,291) .
