HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 860, 495, 450 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 860, 495, 450 is 5 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 860, 495, 450 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 860, 495, 450 is 5.
HCF(860, 495, 450) = 5
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 860, 495, 450 is 5.
Step 1: Since 860 > 495, we apply the division lemma to 860 and 495, to get
860 = 495 x 1 + 365
Step 2: Since the reminder 495 ≠ 0, we apply division lemma to 365 and 495, to get
495 = 365 x 1 + 130
Step 3: We consider the new divisor 365 and the new remainder 130, and apply the division lemma to get
365 = 130 x 2 + 105
We consider the new divisor 130 and the new remainder 105,and apply the division lemma to get
130 = 105 x 1 + 25
We consider the new divisor 105 and the new remainder 25,and apply the division lemma to get
105 = 25 x 4 + 5
We consider the new divisor 25 and the new remainder 5,and apply the division lemma to get
25 = 5 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 860 and 495 is 5
Notice that 5 = HCF(25,5) = HCF(105,25) = HCF(130,105) = HCF(365,130) = HCF(495,365) = HCF(860,495) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 450 > 5, we apply the division lemma to 450 and 5, to get
450 = 5 x 90 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 450 is 5
Notice that 5 = HCF(450,5) .
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 860, 495, 450?
Answer: HCF of 860, 495, 450 is 5 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 860, 495, 450 using Euclid's Algorithm?
Answer: For arbitrary numbers 860, 495, 450 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
