HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 446, 240, 168 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 446, 240, 168 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 446, 240, 168 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 446, 240, 168 is 2.
HCF(446, 240, 168) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 446, 240, 168 is 2.
Step 1: Since 446 > 240, we apply the division lemma to 446 and 240, to get
446 = 240 x 1 + 206
Step 2: Since the reminder 240 ≠ 0, we apply division lemma to 206 and 240, to get
240 = 206 x 1 + 34
Step 3: We consider the new divisor 206 and the new remainder 34, and apply the division lemma to get
206 = 34 x 6 + 2
We consider the new divisor 34 and the new remainder 2, and apply the division lemma to get
34 = 2 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 446 and 240 is 2
Notice that 2 = HCF(34,2) = HCF(206,34) = HCF(240,206) = HCF(446,240) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 168 > 2, we apply the division lemma to 168 and 2, to get
168 = 2 x 84 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 168 is 2
Notice that 2 = HCF(168,2) .
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 446, 240, 168?
Answer: HCF of 446, 240, 168 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 446, 240, 168 using Euclid's Algorithm?
Answer: For arbitrary numbers 446, 240, 168 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
