HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 665, 9430, 5468 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 665, 9430, 5468 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 665, 9430, 5468 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 665, 9430, 5468 is 1.
HCF(665, 9430, 5468) = 1
HCF of 665, 9430, 5468 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 665, 9430, 5468 is 1.
Highest Common Factor of 665,9430,5468 is 1
Step 1: Since 9430 > 665, we apply the division lemma to 9430 and 665, to get
9430 = 665 x 14 + 120
Step 2: Since the reminder 665 ≠ 0, we apply division lemma to 120 and 665, to get
665 = 120 x 5 + 65
Step 3: We consider the new divisor 120 and the new remainder 65, and apply the division lemma to get
120 = 65 x 1 + 55
We consider the new divisor 65 and the new remainder 55,and apply the division lemma to get
65 = 55 x 1 + 10
We consider the new divisor 55 and the new remainder 10,and apply the division lemma to get
55 = 10 x 5 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 665 and 9430 is 5
Notice that 5 = HCF(10,5) = HCF(55,10) = HCF(65,55) = HCF(120,65) = HCF(665,120) = HCF(9430,665) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 5468 > 5, we apply the division lemma to 5468 and 5, to get
5468 = 5 x 1093 + 3
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get
5 = 3 x 1 + 2
Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 5468 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(5468,5) .
