HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 166, 953, 748 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 166, 953, 748 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 166, 953, 748 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 166, 953, 748 is 1.
HCF(166, 953, 748) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 166, 953, 748 is 1.
Step 1: Since 953 > 166, we apply the division lemma to 953 and 166, to get
953 = 166 x 5 + 123
Step 2: Since the reminder 166 ≠ 0, we apply division lemma to 123 and 166, to get
166 = 123 x 1 + 43
Step 3: We consider the new divisor 123 and the new remainder 43, and apply the division lemma to get
123 = 43 x 2 + 37
We consider the new divisor 43 and the new remainder 37,and apply the division lemma to get
43 = 37 x 1 + 6
We consider the new divisor 37 and the new remainder 6,and apply the division lemma to get
37 = 6 x 6 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 166 and 953 is 1
Notice that 1 = HCF(6,1) = HCF(37,6) = HCF(43,37) = HCF(123,43) = HCF(166,123) = HCF(953,166) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 748 > 1, we apply the division lemma to 748 and 1, to get
748 = 1 x 748 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 748 is 1
Notice that 1 = HCF(748,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 166, 953, 748?
Answer: HCF of 166, 953, 748 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 166, 953, 748 using Euclid's Algorithm?
Answer: For arbitrary numbers 166, 953, 748 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
