HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 198, 136, 447 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 198, 136, 447 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 198, 136, 447 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, 136, 447 is 1.
HCF(198, 136, 447) = 1
HCF of 198, 136, 447 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, 136, 447 is 1.
Highest Common Factor of 198,136,447 is 1
Step 1: Since 198 > 136, we apply the division lemma to 198 and 136, to get
198 = 136 x 1 + 62
Step 2: Since the reminder 136 ≠ 0, we apply division lemma to 62 and 136, to get
136 = 62 x 2 + 12
Step 3: We consider the new divisor 62 and the new remainder 12, and apply the division lemma to get
62 = 12 x 5 + 2
We consider the new divisor 12 and the new remainder 2, and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 198 and 136 is 2
Notice that 2 = HCF(12,2) = HCF(62,12) = HCF(136,62) = HCF(198,136) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 447 > 2, we apply the division lemma to 447 and 2, to get
447 = 2 x 223 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 447 is 1
Notice that 1 = HCF(2,1) = HCF(447,2) .
