HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 660, 751, 387 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 660, 751, 387 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 660, 751, 387 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, 751, 387 is 1.
HCF(660, 751, 387) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 660, 751, 387 is 1.
Step 1: Since 751 > 660, we apply the division lemma to 751 and 660, to get
751 = 660 x 1 + 91
Step 2: Since the reminder 660 ≠ 0, we apply division lemma to 91 and 660, to get
660 = 91 x 7 + 23
Step 3: We consider the new divisor 91 and the new remainder 23, and apply the division lemma to get
91 = 23 x 3 + 22
We consider the new divisor 23 and the new remainder 22,and apply the division lemma to get
23 = 22 x 1 + 1
We consider the new divisor 22 and the new remainder 1,and apply the division lemma to get
22 = 1 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 660 and 751 is 1
Notice that 1 = HCF(22,1) = HCF(23,22) = HCF(91,23) = HCF(660,91) = HCF(751,660) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 387 > 1, we apply the division lemma to 387 and 1, to get
387 = 1 x 387 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 387 is 1
Notice that 1 = HCF(387,1) .
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, 751, 387?
Answer: HCF of 660, 751, 387 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 660, 751, 387 using Euclid's Algorithm?
Answer: For arbitrary numbers 660, 751, 387 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
