HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 664, 9479, 7664 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 664, 9479, 7664 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 664, 9479, 7664 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 664, 9479, 7664 is 1.
HCF(664, 9479, 7664) = 1
HCF of 664, 9479, 7664 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 664, 9479, 7664 is 1.
Highest Common Factor of 664,9479,7664 is 1
Step 1: Since 9479 > 664, we apply the division lemma to 9479 and 664, to get
9479 = 664 x 14 + 183
Step 2: Since the reminder 664 ≠ 0, we apply division lemma to 183 and 664, to get
664 = 183 x 3 + 115
Step 3: We consider the new divisor 183 and the new remainder 115, and apply the division lemma to get
183 = 115 x 1 + 68
We consider the new divisor 115 and the new remainder 68,and apply the division lemma to get
115 = 68 x 1 + 47
We consider the new divisor 68 and the new remainder 47,and apply the division lemma to get
68 = 47 x 1 + 21
We consider the new divisor 47 and the new remainder 21,and apply the division lemma to get
47 = 21 x 2 + 5
We consider the new divisor 21 and the new remainder 5,and apply the division lemma to get
21 = 5 x 4 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 664 and 9479 is 1
Notice that 1 = HCF(5,1) = HCF(21,5) = HCF(47,21) = HCF(68,47) = HCF(115,68) = HCF(183,115) = HCF(664,183) = HCF(9479,664) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7664 > 1, we apply the division lemma to 7664 and 1, to get
7664 = 1 x 7664 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 7664 is 1
Notice that 1 = HCF(7664,1) .
