HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 199, 922, 146 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 199, 922, 146 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 199, 922, 146 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 199, 922, 146 is 1.
HCF(199, 922, 146) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 199, 922, 146 is 1.
Step 1: Since 922 > 199, we apply the division lemma to 922 and 199, to get
922 = 199 x 4 + 126
Step 2: Since the reminder 199 ≠ 0, we apply division lemma to 126 and 199, to get
199 = 126 x 1 + 73
Step 3: We consider the new divisor 126 and the new remainder 73, and apply the division lemma to get
126 = 73 x 1 + 53
We consider the new divisor 73 and the new remainder 53,and apply the division lemma to get
73 = 53 x 1 + 20
We consider the new divisor 53 and the new remainder 20,and apply the division lemma to get
53 = 20 x 2 + 13
We consider the new divisor 20 and the new remainder 13,and apply the division lemma to get
20 = 13 x 1 + 7
We consider the new divisor 13 and the new remainder 7,and apply the division lemma to get
13 = 7 x 1 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 199 and 922 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(13,7) = HCF(20,13) = HCF(53,20) = HCF(73,53) = HCF(126,73) = HCF(199,126) = HCF(922,199) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 146 > 1, we apply the division lemma to 146 and 1, to get
146 = 1 x 146 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 146 is 1
Notice that 1 = HCF(146,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
