HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 291, 469, 104 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 291, 469, 104 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 291, 469, 104 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 291, 469, 104 is 1.
HCF(291, 469, 104) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 291, 469, 104 is 1.
Step 1: Since 469 > 291, we apply the division lemma to 469 and 291, to get
469 = 291 x 1 + 178
Step 2: Since the reminder 291 ≠ 0, we apply division lemma to 178 and 291, to get
291 = 178 x 1 + 113
Step 3: We consider the new divisor 178 and the new remainder 113, and apply the division lemma to get
178 = 113 x 1 + 65
We consider the new divisor 113 and the new remainder 65,and apply the division lemma to get
113 = 65 x 1 + 48
We consider the new divisor 65 and the new remainder 48,and apply the division lemma to get
65 = 48 x 1 + 17
We consider the new divisor 48 and the new remainder 17,and apply the division lemma to get
48 = 17 x 2 + 14
We consider the new divisor 17 and the new remainder 14,and apply the division lemma to get
17 = 14 x 1 + 3
We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get
14 = 3 x 4 + 2
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 291 and 469 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(17,14) = HCF(48,17) = HCF(65,48) = HCF(113,65) = HCF(178,113) = HCF(291,178) = HCF(469,291) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 104 > 1, we apply the division lemma to 104 and 1, to get
104 = 1 x 104 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 104 is 1
Notice that 1 = HCF(104,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
