HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 198, 308 i.e. 22 the largest integer that leaves a remainder zero for all numbers.
HCF of 198, 308 is 22 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 198, 308 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 198, 308 is 22.
HCF(198, 308) = 22
HCF of 198, 308 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 198, 308 is 22.
Highest Common Factor of 198,308 is 22
Step 1: Since 308 > 198, we apply the division lemma to 308 and 198, to get
308 = 198 x 1 + 110
Step 2: Since the reminder 198 ≠ 0, we apply division lemma to 110 and 198, to get
198 = 110 x 1 + 88
Step 3: We consider the new divisor 110 and the new remainder 88, and apply the division lemma to get
110 = 88 x 1 + 22
We consider the new divisor 88 and the new remainder 22, and apply the division lemma to get
88 = 22 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 22, the HCF of 198 and 308 is 22
Notice that 22 = HCF(88,22) = HCF(110,88) = HCF(198,110) = HCF(308,198) .
