HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 713, 573 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 870, 713, 573 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 870, 713, 573 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 870, 713, 573 is 1.
HCF(870, 713, 573) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 870, 713, 573 is 1.
Step 1: Since 870 > 713, we apply the division lemma to 870 and 713, to get
870 = 713 x 1 + 157
Step 2: Since the reminder 713 ≠ 0, we apply division lemma to 157 and 713, to get
713 = 157 x 4 + 85
Step 3: We consider the new divisor 157 and the new remainder 85, and apply the division lemma to get
157 = 85 x 1 + 72
We consider the new divisor 85 and the new remainder 72,and apply the division lemma to get
85 = 72 x 1 + 13
We consider the new divisor 72 and the new remainder 13,and apply the division lemma to get
72 = 13 x 5 + 7
We consider the new divisor 13 and the new remainder 7,and apply the division lemma to get
13 = 7 x 1 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 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 870 and 713 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(13,7) = HCF(72,13) = HCF(85,72) = HCF(157,85) = HCF(713,157) = HCF(870,713) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 573 > 1, we apply the division lemma to 573 and 1, to get
573 = 1 x 573 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 573 is 1
Notice that 1 = HCF(573,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 870, 713, 573?
Answer: HCF of 870, 713, 573 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 870, 713, 573 using Euclid's Algorithm?
Answer: For arbitrary numbers 870, 713, 573 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
