HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 574, 763, 857 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 574, 763, 857 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 574, 763, 857 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 574, 763, 857 is 1.
HCF(574, 763, 857) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 574, 763, 857 is 1.
Step 1: Since 763 > 574, we apply the division lemma to 763 and 574, to get
763 = 574 x 1 + 189
Step 2: Since the reminder 574 ≠ 0, we apply division lemma to 189 and 574, to get
574 = 189 x 3 + 7
Step 3: We consider the new divisor 189 and the new remainder 7, and apply the division lemma to get
189 = 7 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 574 and 763 is 7
Notice that 7 = HCF(189,7) = HCF(574,189) = HCF(763,574) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 857 > 7, we apply the division lemma to 857 and 7, to get
857 = 7 x 122 + 3
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 3 and 7, to get
7 = 3 x 2 + 1
Step 3: 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 7 and 857 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(857,7) .
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 574, 763, 857?
Answer: HCF of 574, 763, 857 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 574, 763, 857 using Euclid's Algorithm?
Answer: For arbitrary numbers 574, 763, 857 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
