HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 849, 633, 25 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 849, 633, 25 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 849, 633, 25 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 849, 633, 25 is 1.
HCF(849, 633, 25) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 849, 633, 25 is 1.
Step 1: Since 849 > 633, we apply the division lemma to 849 and 633, to get
849 = 633 x 1 + 216
Step 2: Since the reminder 633 ≠ 0, we apply division lemma to 216 and 633, to get
633 = 216 x 2 + 201
Step 3: We consider the new divisor 216 and the new remainder 201, and apply the division lemma to get
216 = 201 x 1 + 15
We consider the new divisor 201 and the new remainder 15,and apply the division lemma to get
201 = 15 x 13 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 849 and 633 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(201,15) = HCF(216,201) = HCF(633,216) = HCF(849,633) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 25 > 3, we apply the division lemma to 25 and 3, to get
25 = 3 x 8 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 25 is 1
Notice that 1 = HCF(3,1) = HCF(25,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
