HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 150, 642, 500 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 150, 642, 500 is 2 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 150, 642, 500 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 150, 642, 500 is 2.
HCF(150, 642, 500) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 150, 642, 500 is 2.
Step 1: Since 642 > 150, we apply the division lemma to 642 and 150, to get
642 = 150 x 4 + 42
Step 2: Since the reminder 150 ≠ 0, we apply division lemma to 42 and 150, to get
150 = 42 x 3 + 24
Step 3: We consider the new divisor 42 and the new remainder 24, and apply the division lemma to get
42 = 24 x 1 + 18
We consider the new divisor 24 and the new remainder 18,and apply the division lemma to get
24 = 18 x 1 + 6
We consider the new divisor 18 and the new remainder 6,and apply the division lemma to get
18 = 6 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 150 and 642 is 6
Notice that 6 = HCF(18,6) = HCF(24,18) = HCF(42,24) = HCF(150,42) = HCF(642,150) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 500 > 6, we apply the division lemma to 500 and 6, to get
500 = 6 x 83 + 2
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 2 and 6, to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 6 and 500 is 2
Notice that 2 = HCF(6,2) = HCF(500,6) .
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 150, 642, 500?
Answer: HCF of 150, 642, 500 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 150, 642, 500 using Euclid's Algorithm?
Answer: For arbitrary numbers 150, 642, 500 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
