HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 499, 779, 84 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 499, 779, 84 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 499, 779, 84 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 499, 779, 84 is 1.
HCF(499, 779, 84) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 499, 779, 84 is 1.
Step 1: Since 779 > 499, we apply the division lemma to 779 and 499, to get
779 = 499 x 1 + 280
Step 2: Since the reminder 499 ≠ 0, we apply division lemma to 280 and 499, to get
499 = 280 x 1 + 219
Step 3: We consider the new divisor 280 and the new remainder 219, and apply the division lemma to get
280 = 219 x 1 + 61
We consider the new divisor 219 and the new remainder 61,and apply the division lemma to get
219 = 61 x 3 + 36
We consider the new divisor 61 and the new remainder 36,and apply the division lemma to get
61 = 36 x 1 + 25
We consider the new divisor 36 and the new remainder 25,and apply the division lemma to get
36 = 25 x 1 + 11
We consider the new divisor 25 and the new remainder 11,and apply the division lemma to get
25 = 11 x 2 + 3
We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get
11 = 3 x 3 + 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 499 and 779 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(25,11) = HCF(36,25) = HCF(61,36) = HCF(219,61) = HCF(280,219) = HCF(499,280) = HCF(779,499) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 84 > 1, we apply the division lemma to 84 and 1, to get
84 = 1 x 84 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 84 is 1
Notice that 1 = HCF(84,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
