HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 676, 201, 225, 612 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 676, 201, 225, 612 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 676, 201, 225, 612 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 676, 201, 225, 612 is 1.
HCF(676, 201, 225, 612) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 676, 201, 225, 612 is 1.
Step 1: Since 676 > 201, we apply the division lemma to 676 and 201, to get
676 = 201 x 3 + 73
Step 2: Since the reminder 201 ≠ 0, we apply division lemma to 73 and 201, to get
201 = 73 x 2 + 55
Step 3: We consider the new divisor 73 and the new remainder 55, and apply the division lemma to get
73 = 55 x 1 + 18
We consider the new divisor 55 and the new remainder 18,and apply the division lemma to get
55 = 18 x 3 + 1
We consider the new divisor 18 and the new remainder 1,and apply the division lemma to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 676 and 201 is 1
Notice that 1 = HCF(18,1) = HCF(55,18) = HCF(73,55) = HCF(201,73) = HCF(676,201) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 225 > 1, we apply the division lemma to 225 and 1, to get
225 = 1 x 225 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 225 is 1
Notice that 1 = HCF(225,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 612 > 1, we apply the division lemma to 612 and 1, to get
612 = 1 x 612 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 612 is 1
Notice that 1 = HCF(612,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 676, 201, 225, 612?
Answer: HCF of 676, 201, 225, 612 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 676, 201, 225, 612 using Euclid's Algorithm?
Answer: For arbitrary numbers 676, 201, 225, 612 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
