HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 746, 944, 445 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 746, 944, 445 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 746, 944, 445 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 746, 944, 445 is 1.
HCF(746, 944, 445) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 746, 944, 445 is 1.
Step 1: Since 944 > 746, we apply the division lemma to 944 and 746, to get
944 = 746 x 1 + 198
Step 2: Since the reminder 746 ≠ 0, we apply division lemma to 198 and 746, to get
746 = 198 x 3 + 152
Step 3: We consider the new divisor 198 and the new remainder 152, and apply the division lemma to get
198 = 152 x 1 + 46
We consider the new divisor 152 and the new remainder 46,and apply the division lemma to get
152 = 46 x 3 + 14
We consider the new divisor 46 and the new remainder 14,and apply the division lemma to get
46 = 14 x 3 + 4
We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get
14 = 4 x 3 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 746 and 944 is 2
Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(46,14) = HCF(152,46) = HCF(198,152) = HCF(746,198) = HCF(944,746) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 445 > 2, we apply the division lemma to 445 and 2, to get
445 = 2 x 222 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 445 is 1
Notice that 1 = HCF(2,1) = HCF(445,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 746, 944, 445?
Answer: HCF of 746, 944, 445 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 746, 944, 445 using Euclid's Algorithm?
Answer: For arbitrary numbers 746, 944, 445 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
