HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 976, 144, 745 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 976, 144, 745 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 976, 144, 745 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 976, 144, 745 is 1.
HCF(976, 144, 745) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 976, 144, 745 is 1.
Step 1: Since 976 > 144, we apply the division lemma to 976 and 144, to get
976 = 144 x 6 + 112
Step 2: Since the reminder 144 ≠ 0, we apply division lemma to 112 and 144, to get
144 = 112 x 1 + 32
Step 3: We consider the new divisor 112 and the new remainder 32, and apply the division lemma to get
112 = 32 x 3 + 16
We consider the new divisor 32 and the new remainder 16, and apply the division lemma to get
32 = 16 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 16, the HCF of 976 and 144 is 16
Notice that 16 = HCF(32,16) = HCF(112,32) = HCF(144,112) = HCF(976,144) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 745 > 16, we apply the division lemma to 745 and 16, to get
745 = 16 x 46 + 9
Step 2: Since the reminder 16 ≠ 0, we apply division lemma to 9 and 16, to get
16 = 9 x 1 + 7
Step 3: We consider the new divisor 9 and the new remainder 7, and apply the division lemma to get
9 = 7 x 1 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 16 and 745 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(16,9) = HCF(745,16) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 976, 144, 745?
Answer: HCF of 976, 144, 745 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 976, 144, 745 using Euclid's Algorithm?
