HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 729, 786, 48 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 870, 729, 786, 48 is 3 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, 729, 786, 48 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, 729, 786, 48 is 3.
HCF(870, 729, 786, 48) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 870, 729, 786, 48 is 3.
Step 1: Since 870 > 729, we apply the division lemma to 870 and 729, to get
870 = 729 x 1 + 141
Step 2: Since the reminder 729 ≠ 0, we apply division lemma to 141 and 729, to get
729 = 141 x 5 + 24
Step 3: We consider the new divisor 141 and the new remainder 24, and apply the division lemma to get
141 = 24 x 5 + 21
We consider the new divisor 24 and the new remainder 21,and apply the division lemma to get
24 = 21 x 1 + 3
We consider the new divisor 21 and the new remainder 3,and apply the division lemma to get
21 = 3 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 870 and 729 is 3
Notice that 3 = HCF(21,3) = HCF(24,21) = HCF(141,24) = HCF(729,141) = HCF(870,729) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 786 > 3, we apply the division lemma to 786 and 3, to get
786 = 3 x 262 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 786 is 3
Notice that 3 = HCF(786,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 48 > 3, we apply the division lemma to 48 and 3, to get
48 = 3 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 48 is 3
Notice that 3 = HCF(48,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 870, 729, 786, 48?
Answer: HCF of 870, 729, 786, 48 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 870, 729, 786, 48 using Euclid's Algorithm?
Answer: For arbitrary numbers 870, 729, 786, 48 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
