HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 147, 493 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 147, 493 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 147, 493 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 147, 493 is 1.
HCF(147, 493) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 147, 493 is 1.
Step 1: Since 493 > 147, we apply the division lemma to 493 and 147, to get
493 = 147 x 3 + 52
Step 2: Since the reminder 147 ≠ 0, we apply division lemma to 52 and 147, to get
147 = 52 x 2 + 43
Step 3: We consider the new divisor 52 and the new remainder 43, and apply the division lemma to get
52 = 43 x 1 + 9
We consider the new divisor 43 and the new remainder 9,and apply the division lemma to get
43 = 9 x 4 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 147 and 493 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(43,9) = HCF(52,43) = HCF(147,52) = HCF(493,147) .
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 147, 493?
Answer: HCF of 147, 493 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 147, 493 using Euclid's Algorithm?
Answer: For arbitrary numbers 147, 493 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
