HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 150, 720 i.e. 30 the largest integer that leaves a remainder zero for all numbers.
HCF of 150, 720 is 30 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, 720 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, 720 is 30.
HCF(150, 720) = 30
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 150, 720 is 30.
Step 1: Since 720 > 150, we apply the division lemma to 720 and 150, to get
720 = 150 x 4 + 120
Step 2: Since the reminder 150 ≠ 0, we apply division lemma to 120 and 150, to get
150 = 120 x 1 + 30
Step 3: We consider the new divisor 120 and the new remainder 30, and apply the division lemma to get
120 = 30 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 30, the HCF of 150 and 720 is 30
Notice that 30 = HCF(120,30) = HCF(150,120) = HCF(720,150) .
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, 720?
Answer: HCF of 150, 720 is 30 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 150, 720 using Euclid's Algorithm?
Answer: For arbitrary numbers 150, 720 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
