HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 244, 155 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 244, 155 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 244, 155 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 244, 155 is 1.
HCF(244, 155) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 244, 155 is 1.
Step 1: Since 244 > 155, we apply the division lemma to 244 and 155, to get
244 = 155 x 1 + 89
Step 2: Since the reminder 155 ≠ 0, we apply division lemma to 89 and 155, to get
155 = 89 x 1 + 66
Step 3: We consider the new divisor 89 and the new remainder 66, and apply the division lemma to get
89 = 66 x 1 + 23
We consider the new divisor 66 and the new remainder 23,and apply the division lemma to get
66 = 23 x 2 + 20
We consider the new divisor 23 and the new remainder 20,and apply the division lemma to get
23 = 20 x 1 + 3
We consider the new divisor 20 and the new remainder 3,and apply the division lemma to get
20 = 3 x 6 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 244 and 155 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(23,20) = HCF(66,23) = HCF(89,66) = HCF(155,89) = HCF(244,155) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 244, 155?
Answer: HCF of 244, 155 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 244, 155 using Euclid's Algorithm?
Answer: For arbitrary numbers 244, 155 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
