HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 172, 518, 98 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 172, 518, 98 is 2 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 172, 518, 98 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 172, 518, 98 is 2.
HCF(172, 518, 98) = 2
HCF of 172, 518, 98 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 172, 518, 98 is 2.
Highest Common Factor of 172,518,98 is 2
Step 1: Since 518 > 172, we apply the division lemma to 518 and 172, to get
518 = 172 x 3 + 2
Step 2: Since the reminder 172 ≠ 0, we apply division lemma to 2 and 172, to get
172 = 2 x 86 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 172 and 518 is 2
Notice that 2 = HCF(172,2) = HCF(518,172) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 98 > 2, we apply the division lemma to 98 and 2, to get
98 = 2 x 49 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 98 is 2
Notice that 2 = HCF(98,2) .
