HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2655, 8472 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 2655, 8472 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 2655, 8472 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 2655, 8472 is 3.
HCF(2655, 8472) = 3
HCF of 2655, 8472 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 2655, 8472 is 3.
Highest Common Factor of 2655,8472 is 3
Step 1: Since 8472 > 2655, we apply the division lemma to 8472 and 2655, to get
8472 = 2655 x 3 + 507
Step 2: Since the reminder 2655 ≠ 0, we apply division lemma to 507 and 2655, to get
2655 = 507 x 5 + 120
Step 3: We consider the new divisor 507 and the new remainder 120, and apply the division lemma to get
507 = 120 x 4 + 27
We consider the new divisor 120 and the new remainder 27,and apply the division lemma to get
120 = 27 x 4 + 12
We consider the new divisor 27 and the new remainder 12,and apply the division lemma to get
27 = 12 x 2 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 2655 and 8472 is 3
Notice that 3 = HCF(12,3) = HCF(27,12) = HCF(120,27) = HCF(507,120) = HCF(2655,507) = HCF(8472,2655) .
