HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 254, 166, 538 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 254, 166, 538 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 254, 166, 538 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 254, 166, 538 is 2.
HCF(254, 166, 538) = 2
HCF of 254, 166, 538 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 254, 166, 538 is 2.
Highest Common Factor of 254,166,538 is 2
Step 1: Since 254 > 166, we apply the division lemma to 254 and 166, to get
254 = 166 x 1 + 88
Step 2: Since the reminder 166 ≠ 0, we apply division lemma to 88 and 166, to get
166 = 88 x 1 + 78
Step 3: We consider the new divisor 88 and the new remainder 78, and apply the division lemma to get
88 = 78 x 1 + 10
We consider the new divisor 78 and the new remainder 10,and apply the division lemma to get
78 = 10 x 7 + 8
We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 254 and 166 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(78,10) = HCF(88,78) = HCF(166,88) = HCF(254,166) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 538 > 2, we apply the division lemma to 538 and 2, to get
538 = 2 x 269 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 538 is 2
Notice that 2 = HCF(538,2) .
