HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 951, 502, 790 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 951, 502, 790 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 951, 502, 790 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 951, 502, 790 is 1.
HCF(951, 502, 790) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 951, 502, 790 is 1.
Step 1: Since 951 > 502, we apply the division lemma to 951 and 502, to get
951 = 502 x 1 + 449
Step 2: Since the reminder 502 ≠ 0, we apply division lemma to 449 and 502, to get
502 = 449 x 1 + 53
Step 3: We consider the new divisor 449 and the new remainder 53, and apply the division lemma to get
449 = 53 x 8 + 25
We consider the new divisor 53 and the new remainder 25,and apply the division lemma to get
53 = 25 x 2 + 3
We consider the new divisor 25 and the new remainder 3,and apply the division lemma to get
25 = 3 x 8 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 951 and 502 is 1
Notice that 1 = HCF(3,1) = HCF(25,3) = HCF(53,25) = HCF(449,53) = HCF(502,449) = HCF(951,502) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 790 > 1, we apply the division lemma to 790 and 1, to get
790 = 1 x 790 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 790 is 1
Notice that 1 = HCF(790,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 951, 502, 790?
Answer: HCF of 951, 502, 790 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 951, 502, 790 using Euclid's Algorithm?
Answer: For arbitrary numbers 951, 502, 790 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
