HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 472, 748, 618 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 472, 748, 618 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 472, 748, 618 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 472, 748, 618 is 2.
HCF(472, 748, 618) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 472, 748, 618 is 2.
Step 1: Since 748 > 472, we apply the division lemma to 748 and 472, to get
748 = 472 x 1 + 276
Step 2: Since the reminder 472 ≠ 0, we apply division lemma to 276 and 472, to get
472 = 276 x 1 + 196
Step 3: We consider the new divisor 276 and the new remainder 196, and apply the division lemma to get
276 = 196 x 1 + 80
We consider the new divisor 196 and the new remainder 80,and apply the division lemma to get
196 = 80 x 2 + 36
We consider the new divisor 80 and the new remainder 36,and apply the division lemma to get
80 = 36 x 2 + 8
We consider the new divisor 36 and the new remainder 8,and apply the division lemma to get
36 = 8 x 4 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 472 and 748 is 4
Notice that 4 = HCF(8,4) = HCF(36,8) = HCF(80,36) = HCF(196,80) = HCF(276,196) = HCF(472,276) = HCF(748,472) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 618 > 4, we apply the division lemma to 618 and 4, to get
618 = 4 x 154 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 618 is 2
Notice that 2 = HCF(4,2) = HCF(618,4) .
Here are some samples of HCF using Euclid's Algorithm calculations.
