HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 425, 198 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 425, 198 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 425, 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 425, 198 is 1.
HCF(425, 198) = 1
HCF of 425, 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 425, 198 is 1.
Highest Common Factor of 425,198 is 1
Step 1: Since 425 > 198, we apply the division lemma to 425 and 198, to get
425 = 198 x 2 + 29
Step 2: Since the reminder 198 ≠ 0, we apply division lemma to 29 and 198, to get
198 = 29 x 6 + 24
Step 3: We consider the new divisor 29 and the new remainder 24, and apply the division lemma to get
29 = 24 x 1 + 5
We consider the new divisor 24 and the new remainder 5,and apply the division lemma to get
24 = 5 x 4 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 425 and 198 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(24,5) = HCF(29,24) = HCF(198,29) = HCF(425,198) .
