HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 660, 772, 456 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 660, 772, 456 is 4 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 660, 772, 456 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 660, 772, 456 is 4.
HCF(660, 772, 456) = 4
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 660, 772, 456 is 4.
Step 1: Since 772 > 660, we apply the division lemma to 772 and 660, to get
772 = 660 x 1 + 112
Step 2: Since the reminder 660 ≠ 0, we apply division lemma to 112 and 660, to get
660 = 112 x 5 + 100
Step 3: We consider the new divisor 112 and the new remainder 100, and apply the division lemma to get
112 = 100 x 1 + 12
We consider the new divisor 100 and the new remainder 12,and apply the division lemma to get
100 = 12 x 8 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 660 and 772 is 4
Notice that 4 = HCF(12,4) = HCF(100,12) = HCF(112,100) = HCF(660,112) = HCF(772,660) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 456 > 4, we apply the division lemma to 456 and 4, to get
456 = 4 x 114 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 456 is 4
Notice that 4 = HCF(456,4) .
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 660, 772, 456?
Answer: HCF of 660, 772, 456 is 4 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 660, 772, 456 using Euclid's Algorithm?
Answer: For arbitrary numbers 660, 772, 456 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
