HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 492, 868, 136 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 492, 868, 136 is 4 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 492, 868, 136 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 492, 868, 136 is 4.
HCF(492, 868, 136) = 4
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 492, 868, 136 is 4.
Step 1: Since 868 > 492, we apply the division lemma to 868 and 492, to get
868 = 492 x 1 + 376
Step 2: Since the reminder 492 ≠ 0, we apply division lemma to 376 and 492, to get
492 = 376 x 1 + 116
Step 3: We consider the new divisor 376 and the new remainder 116, and apply the division lemma to get
376 = 116 x 3 + 28
We consider the new divisor 116 and the new remainder 28,and apply the division lemma to get
116 = 28 x 4 + 4
We consider the new divisor 28 and the new remainder 4,and apply the division lemma to get
28 = 4 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 492 and 868 is 4
Notice that 4 = HCF(28,4) = HCF(116,28) = HCF(376,116) = HCF(492,376) = HCF(868,492) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 136 > 4, we apply the division lemma to 136 and 4, to get
136 = 4 x 34 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 136 is 4
Notice that 4 = HCF(136,4) .
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 492, 868, 136?
Answer: HCF of 492, 868, 136 is 4 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 492, 868, 136 using Euclid's Algorithm?
Answer: For arbitrary numbers 492, 868, 136 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
