HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 285, 840, 932 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 285, 840, 932 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 285, 840, 932 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 285, 840, 932 is 1.
HCF(285, 840, 932) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 285, 840, 932 is 1.
Step 1: Since 840 > 285, we apply the division lemma to 840 and 285, to get
840 = 285 x 2 + 270
Step 2: Since the reminder 285 ≠ 0, we apply division lemma to 270 and 285, to get
285 = 270 x 1 + 15
Step 3: We consider the new divisor 270 and the new remainder 15, and apply the division lemma to get
270 = 15 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 285 and 840 is 15
Notice that 15 = HCF(270,15) = HCF(285,270) = HCF(840,285) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 932 > 15, we apply the division lemma to 932 and 15, to get
932 = 15 x 62 + 2
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 2 and 15, to get
15 = 2 x 7 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 15 and 932 is 1
Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(932,15) .
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 285, 840, 932?
Answer: HCF of 285, 840, 932 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 285, 840, 932 using Euclid's Algorithm?
Answer: For arbitrary numbers 285, 840, 932 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
