HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 274, 198 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 274, 198 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 274, 198 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 274, 198 is 2.
HCF(274, 198) = 2
HCF of 274, 198 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 274, 198 is 2.
Highest Common Factor of 274,198 is 2
Step 1: Since 274 > 198, we apply the division lemma to 274 and 198, to get
274 = 198 x 1 + 76
Step 2: Since the reminder 198 ≠ 0, we apply division lemma to 76 and 198, to get
198 = 76 x 2 + 46
Step 3: We consider the new divisor 76 and the new remainder 46, and apply the division lemma to get
76 = 46 x 1 + 30
We consider the new divisor 46 and the new remainder 30,and apply the division lemma to get
46 = 30 x 1 + 16
We consider the new divisor 30 and the new remainder 16,and apply the division lemma to get
30 = 16 x 1 + 14
We consider the new divisor 16 and the new remainder 14,and apply the division lemma to get
16 = 14 x 1 + 2
We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 274 and 198 is 2
Notice that 2 = HCF(14,2) = HCF(16,14) = HCF(30,16) = HCF(46,30) = HCF(76,46) = HCF(198,76) = HCF(274,198) .
