HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 421, 377 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 421, 377 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 421, 377 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 421, 377 is 1.
HCF(421, 377) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 421, 377 is 1.
Step 1: Since 421 > 377, we apply the division lemma to 421 and 377, to get
421 = 377 x 1 + 44
Step 2: Since the reminder 377 ≠ 0, we apply division lemma to 44 and 377, to get
377 = 44 x 8 + 25
Step 3: We consider the new divisor 44 and the new remainder 25, and apply the division lemma to get
44 = 25 x 1 + 19
We consider the new divisor 25 and the new remainder 19,and apply the division lemma to get
25 = 19 x 1 + 6
We consider the new divisor 19 and the new remainder 6,and apply the division lemma to get
19 = 6 x 3 + 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 421 and 377 is 1
Notice that 1 = HCF(6,1) = HCF(19,6) = HCF(25,19) = HCF(44,25) = HCF(377,44) = HCF(421,377) .
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 421, 377?
Answer: HCF of 421, 377 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 421, 377 using Euclid's Algorithm?
Answer: For arbitrary numbers 421, 377 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
