HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 730, 236 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 870, 730, 236 is 2 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, 730, 236 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, 730, 236 is 2.
HCF(870, 730, 236) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 870, 730, 236 is 2.
Step 1: Since 870 > 730, we apply the division lemma to 870 and 730, to get
870 = 730 x 1 + 140
Step 2: Since the reminder 730 ≠ 0, we apply division lemma to 140 and 730, to get
730 = 140 x 5 + 30
Step 3: We consider the new divisor 140 and the new remainder 30, and apply the division lemma to get
140 = 30 x 4 + 20
We consider the new divisor 30 and the new remainder 20,and apply the division lemma to get
30 = 20 x 1 + 10
We consider the new divisor 20 and the new remainder 10,and apply the division lemma to get
20 = 10 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 870 and 730 is 10
Notice that 10 = HCF(20,10) = HCF(30,20) = HCF(140,30) = HCF(730,140) = HCF(870,730) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 236 > 10, we apply the division lemma to 236 and 10, to get
236 = 10 x 23 + 6
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 6 and 10, to get
10 = 6 x 1 + 4
Step 3: We consider the new divisor 6 and the new remainder 4, and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 10 and 236 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(236,10) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 870, 730, 236?
Answer: HCF of 870, 730, 236 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 870, 730, 236 using Euclid's Algorithm?
