HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 499, 637, 849 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 499, 637, 849 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, 637, 849 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, 637, 849 is 1.
HCF(499, 637, 849) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 499, 637, 849 is 1.
Step 1: Since 637 > 499, we apply the division lemma to 637 and 499, to get
637 = 499 x 1 + 138
Step 2: Since the reminder 499 ≠ 0, we apply division lemma to 138 and 499, to get
499 = 138 x 3 + 85
Step 3: We consider the new divisor 138 and the new remainder 85, and apply the division lemma to get
138 = 85 x 1 + 53
We consider the new divisor 85 and the new remainder 53,and apply the division lemma to get
85 = 53 x 1 + 32
We consider the new divisor 53 and the new remainder 32,and apply the division lemma to get
53 = 32 x 1 + 21
We consider the new divisor 32 and the new remainder 21,and apply the division lemma to get
32 = 21 x 1 + 11
We consider the new divisor 21 and the new remainder 11,and apply the division lemma to get
21 = 11 x 1 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 499 and 637 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(32,21) = HCF(53,32) = HCF(85,53) = HCF(138,85) = HCF(499,138) = HCF(637,499) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 849 > 1, we apply the division lemma to 849 and 1, to get
849 = 1 x 849 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 849 is 1
Notice that 1 = HCF(849,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
