HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 409, 656, 496 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 409, 656, 496 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 409, 656, 496 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 409, 656, 496 is 1.
HCF(409, 656, 496) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 409, 656, 496 is 1.
Step 1: Since 656 > 409, we apply the division lemma to 656 and 409, to get
656 = 409 x 1 + 247
Step 2: Since the reminder 409 ≠ 0, we apply division lemma to 247 and 409, to get
409 = 247 x 1 + 162
Step 3: We consider the new divisor 247 and the new remainder 162, and apply the division lemma to get
247 = 162 x 1 + 85
We consider the new divisor 162 and the new remainder 85,and apply the division lemma to get
162 = 85 x 1 + 77
We consider the new divisor 85 and the new remainder 77,and apply the division lemma to get
85 = 77 x 1 + 8
We consider the new divisor 77 and the new remainder 8,and apply the division lemma to get
77 = 8 x 9 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 409 and 656 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(77,8) = HCF(85,77) = HCF(162,85) = HCF(247,162) = HCF(409,247) = HCF(656,409) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 496 > 1, we apply the division lemma to 496 and 1, to get
496 = 1 x 496 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 496 is 1
Notice that 1 = HCF(496,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
