HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 635, 508, 362 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 635, 508, 362 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 635, 508, 362 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 635, 508, 362 is 1.
HCF(635, 508, 362) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 635, 508, 362 is 1.
Step 1: Since 635 > 508, we apply the division lemma to 635 and 508, to get
635 = 508 x 1 + 127
Step 2: Since the reminder 508 ≠ 0, we apply division lemma to 127 and 508, to get
508 = 127 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 127, the HCF of 635 and 508 is 127
Notice that 127 = HCF(508,127) = HCF(635,508) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 362 > 127, we apply the division lemma to 362 and 127, to get
362 = 127 x 2 + 108
Step 2: Since the reminder 127 ≠ 0, we apply division lemma to 108 and 127, to get
127 = 108 x 1 + 19
Step 3: We consider the new divisor 108 and the new remainder 19, and apply the division lemma to get
108 = 19 x 5 + 13
We consider the new divisor 19 and the new remainder 13,and apply the division lemma to get
19 = 13 x 1 + 6
We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get
13 = 6 x 2 + 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 127 and 362 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(108,19) = HCF(127,108) = HCF(362,127) .
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 635, 508, 362?
Answer: HCF of 635, 508, 362 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 635, 508, 362 using Euclid's Algorithm?
Answer: For arbitrary numbers 635, 508, 362 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
