HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7618, 9415, 87390 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 7618, 9415, 87390 is 1 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 7618, 9415, 87390 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 7618, 9415, 87390 is 1.
HCF(7618, 9415, 87390) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7618, 9415, 87390 is 1.
Step 1: Since 9415 > 7618, we apply the division lemma to 9415 and 7618, to get
9415 = 7618 x 1 + 1797
Step 2: Since the reminder 7618 ≠ 0, we apply division lemma to 1797 and 7618, to get
7618 = 1797 x 4 + 430
Step 3: We consider the new divisor 1797 and the new remainder 430, and apply the division lemma to get
1797 = 430 x 4 + 77
We consider the new divisor 430 and the new remainder 77,and apply the division lemma to get
430 = 77 x 5 + 45
We consider the new divisor 77 and the new remainder 45,and apply the division lemma to get
77 = 45 x 1 + 32
We consider the new divisor 45 and the new remainder 32,and apply the division lemma to get
45 = 32 x 1 + 13
We consider the new divisor 32 and the new remainder 13,and apply the division lemma to get
32 = 13 x 2 + 6
We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get
13 = 6 x 2 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7618 and 9415 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(32,13) = HCF(45,32) = HCF(77,45) = HCF(430,77) = HCF(1797,430) = HCF(7618,1797) = HCF(9415,7618) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 87390 > 1, we apply the division lemma to 87390 and 1, to get
87390 = 1 x 87390 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 87390 is 1
Notice that 1 = HCF(87390,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
