HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 648, 954, 860 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 648, 954, 860 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 648, 954, 860 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 648, 954, 860 is 2.
HCF(648, 954, 860) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 648, 954, 860 is 2.
Step 1: Since 954 > 648, we apply the division lemma to 954 and 648, to get
954 = 648 x 1 + 306
Step 2: Since the reminder 648 ≠ 0, we apply division lemma to 306 and 648, to get
648 = 306 x 2 + 36
Step 3: We consider the new divisor 306 and the new remainder 36, and apply the division lemma to get
306 = 36 x 8 + 18
We consider the new divisor 36 and the new remainder 18, and apply the division lemma to get
36 = 18 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 648 and 954 is 18
Notice that 18 = HCF(36,18) = HCF(306,36) = HCF(648,306) = HCF(954,648) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 860 > 18, we apply the division lemma to 860 and 18, to get
860 = 18 x 47 + 14
Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 14 and 18, to get
18 = 14 x 1 + 4
Step 3: We consider the new divisor 14 and the new remainder 4, and apply the division lemma to get
14 = 4 x 3 + 2
We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 18 and 860 is 2
Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(18,14) = HCF(860,18) .
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 648, 954, 860?
Answer: HCF of 648, 954, 860 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 648, 954, 860 using Euclid's Algorithm?
Answer: For arbitrary numbers 648, 954, 860 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
