HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 479, 660, 76 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 479, 660, 76 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 479, 660, 76 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 479, 660, 76 is 1.
HCF(479, 660, 76) = 1
HCF of 479, 660, 76 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 479, 660, 76 is 1.
Highest Common Factor of 479,660,76 is 1
Step 1: Since 660 > 479, we apply the division lemma to 660 and 479, to get
660 = 479 x 1 + 181
Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 181 and 479, to get
479 = 181 x 2 + 117
Step 3: We consider the new divisor 181 and the new remainder 117, and apply the division lemma to get
181 = 117 x 1 + 64
We consider the new divisor 117 and the new remainder 64,and apply the division lemma to get
117 = 64 x 1 + 53
We consider the new divisor 64 and the new remainder 53,and apply the division lemma to get
64 = 53 x 1 + 11
We consider the new divisor 53 and the new remainder 11,and apply the division lemma to get
53 = 11 x 4 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 479 and 660 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(53,11) = HCF(64,53) = HCF(117,64) = HCF(181,117) = HCF(479,181) = HCF(660,479) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 76 > 1, we apply the division lemma to 76 and 1, to get
76 = 1 x 76 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 76 is 1
Notice that 1 = HCF(76,1) .
