HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 245, 525, 276 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 245, 525, 276 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 245, 525, 276 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 245, 525, 276 is 1.
HCF(245, 525, 276) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 245, 525, 276 is 1.
Step 1: Since 525 > 245, we apply the division lemma to 525 and 245, to get
525 = 245 x 2 + 35
Step 2: Since the reminder 245 ≠ 0, we apply division lemma to 35 and 245, to get
245 = 35 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 35, the HCF of 245 and 525 is 35
Notice that 35 = HCF(245,35) = HCF(525,245) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 276 > 35, we apply the division lemma to 276 and 35, to get
276 = 35 x 7 + 31
Step 2: Since the reminder 35 ≠ 0, we apply division lemma to 31 and 35, to get
35 = 31 x 1 + 4
Step 3: We consider the new divisor 31 and the new remainder 4, and apply the division lemma to get
31 = 4 x 7 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
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 35 and 276 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(31,4) = HCF(35,31) = HCF(276,35) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 245, 525, 276?
Answer: HCF of 245, 525, 276 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 245, 525, 276 using Euclid's Algorithm?
Answer: For arbitrary numbers 245, 525, 276 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
