HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 125, 622, 678, 12 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 125, 622, 678, 12 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 125, 622, 678, 12 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 125, 622, 678, 12 is 1.
HCF(125, 622, 678, 12) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 125, 622, 678, 12 is 1.
Step 1: Since 622 > 125, we apply the division lemma to 622 and 125, to get
622 = 125 x 4 + 122
Step 2: Since the reminder 125 ≠ 0, we apply division lemma to 122 and 125, to get
125 = 122 x 1 + 3
Step 3: We consider the new divisor 122 and the new remainder 3, and apply the division lemma to get
122 = 3 x 40 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
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 125 and 622 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(122,3) = HCF(125,122) = HCF(622,125) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 678 > 1, we apply the division lemma to 678 and 1, to get
678 = 1 x 678 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 678 is 1
Notice that 1 = HCF(678,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 12 > 1, we apply the division lemma to 12 and 1, to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 12 is 1
Notice that 1 = HCF(12,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 125, 622, 678, 12?
Answer: HCF of 125, 622, 678, 12 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 125, 622, 678, 12 using Euclid's Algorithm?
Answer: For arbitrary numbers 125, 622, 678, 12 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
