HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 148, 851, 123 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 148, 851, 123 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 148, 851, 123 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 148, 851, 123 is 1.
HCF(148, 851, 123) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 148, 851, 123 is 1.
Step 1: Since 851 > 148, we apply the division lemma to 851 and 148, to get
851 = 148 x 5 + 111
Step 2: Since the reminder 148 ≠ 0, we apply division lemma to 111 and 148, to get
148 = 111 x 1 + 37
Step 3: We consider the new divisor 111 and the new remainder 37, and apply the division lemma to get
111 = 37 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 37, the HCF of 148 and 851 is 37
Notice that 37 = HCF(111,37) = HCF(148,111) = HCF(851,148) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 123 > 37, we apply the division lemma to 123 and 37, to get
123 = 37 x 3 + 12
Step 2: Since the reminder 37 ≠ 0, we apply division lemma to 12 and 37, to get
37 = 12 x 3 + 1
Step 3: We consider the new divisor 12 and the new remainder 1, and apply the division lemma 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 37 and 123 is 1
Notice that 1 = HCF(12,1) = HCF(37,12) = HCF(123,37) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 148, 851, 123?
Answer: HCF of 148, 851, 123 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 148, 851, 123 using Euclid's Algorithm?
Answer: For arbitrary numbers 148, 851, 123 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
