HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 469, 198, 447 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 469, 198, 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 469, 198, 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 469, 198, 447 is 1.
HCF(469, 198, 447) = 1
HCF of 469, 198, 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 469, 198, 447 is 1.
Highest Common Factor of 469,198,447 is 1
Step 1: Since 469 > 198, we apply the division lemma to 469 and 198, to get
469 = 198 x 2 + 73
Step 2: Since the reminder 198 ≠ 0, we apply division lemma to 73 and 198, to get
198 = 73 x 2 + 52
Step 3: We consider the new divisor 73 and the new remainder 52, and apply the division lemma to get
73 = 52 x 1 + 21
We consider the new divisor 52 and the new remainder 21,and apply the division lemma to get
52 = 21 x 2 + 10
We consider the new divisor 21 and the new remainder 10,and apply the division lemma to get
21 = 10 x 2 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 469 and 198 is 1
Notice that 1 = HCF(10,1) = HCF(21,10) = HCF(52,21) = HCF(73,52) = HCF(198,73) = HCF(469,198) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 447 > 1, we apply the division lemma to 447 and 1, to get
447 = 1 x 447 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 447 is 1
Notice that 1 = HCF(447,1) .
