HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 144, 198, 119 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 144, 198, 119 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 144, 198, 119 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 144, 198, 119 is 1.
HCF(144, 198, 119) = 1
HCF of 144, 198, 119 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 144, 198, 119 is 1.
Highest Common Factor of 144,198,119 is 1
Step 1: Since 198 > 144, we apply the division lemma to 198 and 144, to get
198 = 144 x 1 + 54
Step 2: Since the reminder 144 ≠ 0, we apply division lemma to 54 and 144, to get
144 = 54 x 2 + 36
Step 3: We consider the new divisor 54 and the new remainder 36, and apply the division lemma to get
54 = 36 x 1 + 18
We consider the new divisor 36 and the new remainder 18, and apply the division lemma to get
36 = 18 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 144 and 198 is 18
Notice that 18 = HCF(36,18) = HCF(54,36) = HCF(144,54) = HCF(198,144) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 119 > 18, we apply the division lemma to 119 and 18, to get
119 = 18 x 6 + 11
Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 11 and 18, to get
18 = 11 x 1 + 7
Step 3: We consider the new divisor 11 and the new remainder 7, and apply the division lemma to get
11 = 7 x 1 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 18 and 119 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(18,11) = HCF(119,18) .
