HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 202, 488, 97 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 202, 488, 97 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 202, 488, 97 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 202, 488, 97 is 1.
HCF(202, 488, 97) = 1
HCF of 202, 488, 97 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 202, 488, 97 is 1.
Highest Common Factor of 202,488,97 is 1
Step 1: Since 488 > 202, we apply the division lemma to 488 and 202, to get
488 = 202 x 2 + 84
Step 2: Since the reminder 202 ≠ 0, we apply division lemma to 84 and 202, to get
202 = 84 x 2 + 34
Step 3: We consider the new divisor 84 and the new remainder 34, and apply the division lemma to get
84 = 34 x 2 + 16
We consider the new divisor 34 and the new remainder 16,and apply the division lemma to get
34 = 16 x 2 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 202 and 488 is 2
Notice that 2 = HCF(16,2) = HCF(34,16) = HCF(84,34) = HCF(202,84) = HCF(488,202) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 97 > 2, we apply the division lemma to 97 and 2, to get
97 = 2 x 48 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 97 is 1
Notice that 1 = HCF(2,1) = HCF(97,2) .
