HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 744, 155, 760 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 744, 155, 760 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 744, 155, 760 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 744, 155, 760 is 1.
HCF(744, 155, 760) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 744, 155, 760 is 1.
Step 1: Since 744 > 155, we apply the division lemma to 744 and 155, to get
744 = 155 x 4 + 124
Step 2: Since the reminder 155 ≠ 0, we apply division lemma to 124 and 155, to get
155 = 124 x 1 + 31
Step 3: We consider the new divisor 124 and the new remainder 31, and apply the division lemma to get
124 = 31 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 31, the HCF of 744 and 155 is 31
Notice that 31 = HCF(124,31) = HCF(155,124) = HCF(744,155) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 760 > 31, we apply the division lemma to 760 and 31, to get
760 = 31 x 24 + 16
Step 2: Since the reminder 31 ≠ 0, we apply division lemma to 16 and 31, to get
31 = 16 x 1 + 15
Step 3: We consider the new divisor 16 and the new remainder 15, and apply the division lemma to get
16 = 15 x 1 + 1
We consider the new divisor 15 and the new remainder 1, and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 31 and 760 is 1
Notice that 1 = HCF(15,1) = HCF(16,15) = HCF(31,16) = HCF(760,31) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 744, 155, 760?
Answer: HCF of 744, 155, 760 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 744, 155, 760 using Euclid's Algorithm?
Answer: For arbitrary numbers 744, 155, 760 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
