HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 618, 452 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 870, 618, 452 is 2 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 870, 618, 452 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 870, 618, 452 is 2.
HCF(870, 618, 452) = 2
HCF of 870, 618, 452 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 870, 618, 452 is 2.
Highest Common Factor of 870,618,452 is 2
Step 1: Since 870 > 618, we apply the division lemma to 870 and 618, to get
870 = 618 x 1 + 252
Step 2: Since the reminder 618 ≠ 0, we apply division lemma to 252 and 618, to get
618 = 252 x 2 + 114
Step 3: We consider the new divisor 252 and the new remainder 114, and apply the division lemma to get
252 = 114 x 2 + 24
We consider the new divisor 114 and the new remainder 24,and apply the division lemma to get
114 = 24 x 4 + 18
We consider the new divisor 24 and the new remainder 18,and apply the division lemma to get
24 = 18 x 1 + 6
We consider the new divisor 18 and the new remainder 6,and apply the division lemma to get
18 = 6 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 870 and 618 is 6
Notice that 6 = HCF(18,6) = HCF(24,18) = HCF(114,24) = HCF(252,114) = HCF(618,252) = HCF(870,618) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 452 > 6, we apply the division lemma to 452 and 6, to get
452 = 6 x 75 + 2
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 2 and 6, to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 6 and 452 is 2
Notice that 2 = HCF(6,2) = HCF(452,6) .
