HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 419, 280, 722 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 419, 280, 722 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 419, 280, 722 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 419, 280, 722 is 1.
HCF(419, 280, 722) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 419, 280, 722 is 1.
Step 1: Since 419 > 280, we apply the division lemma to 419 and 280, to get
419 = 280 x 1 + 139
Step 2: Since the reminder 280 ≠ 0, we apply division lemma to 139 and 280, to get
280 = 139 x 2 + 2
Step 3: We consider the new divisor 139 and the new remainder 2, and apply the division lemma to get
139 = 2 x 69 + 1
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 419 and 280 is 1
Notice that 1 = HCF(2,1) = HCF(139,2) = HCF(280,139) = HCF(419,280) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 722 > 1, we apply the division lemma to 722 and 1, to get
722 = 1 x 722 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 722 is 1
Notice that 1 = HCF(722,1) .
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 419, 280, 722?
Answer: HCF of 419, 280, 722 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 419, 280, 722 using Euclid's Algorithm?
Answer: For arbitrary numbers 419, 280, 722 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
