HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 180, 6957, 5015 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 180, 6957, 5015 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 180, 6957, 5015 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 180, 6957, 5015 is 1.
HCF(180, 6957, 5015) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 180, 6957, 5015 is 1.
Step 1: Since 6957 > 180, we apply the division lemma to 6957 and 180, to get
6957 = 180 x 38 + 117
Step 2: Since the reminder 180 ≠ 0, we apply division lemma to 117 and 180, to get
180 = 117 x 1 + 63
Step 3: We consider the new divisor 117 and the new remainder 63, and apply the division lemma to get
117 = 63 x 1 + 54
We consider the new divisor 63 and the new remainder 54,and apply the division lemma to get
63 = 54 x 1 + 9
We consider the new divisor 54 and the new remainder 9,and apply the division lemma to get
54 = 9 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 180 and 6957 is 9
Notice that 9 = HCF(54,9) = HCF(63,54) = HCF(117,63) = HCF(180,117) = HCF(6957,180) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 5015 > 9, we apply the division lemma to 5015 and 9, to get
5015 = 9 x 557 + 2
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 2 and 9, to get
9 = 2 x 4 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 9 and 5015 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(5015,9) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 180, 6957, 5015?
Answer: HCF of 180, 6957, 5015 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 180, 6957, 5015 using Euclid's Algorithm?
Answer: For arbitrary numbers 180, 6957, 5015 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
