HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 496, 985, 861 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 496, 985, 861 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 496, 985, 861 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 496, 985, 861 is 1.
HCF(496, 985, 861) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 496, 985, 861 is 1.
Step 1: Since 985 > 496, we apply the division lemma to 985 and 496, to get
985 = 496 x 1 + 489
Step 2: Since the reminder 496 ≠ 0, we apply division lemma to 489 and 496, to get
496 = 489 x 1 + 7
Step 3: We consider the new divisor 489 and the new remainder 7, and apply the division lemma to get
489 = 7 x 69 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 496 and 985 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(489,7) = HCF(496,489) = HCF(985,496) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 861 > 1, we apply the division lemma to 861 and 1, to get
861 = 1 x 861 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 861 is 1
Notice that 1 = HCF(861,1) .
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 496, 985, 861?
Answer: HCF of 496, 985, 861 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 496, 985, 861 using Euclid's Algorithm?
Answer: For arbitrary numbers 496, 985, 861 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
