HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 724, 747, 974 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 724, 747, 974 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 724, 747, 974 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 724, 747, 974 is 1.
HCF(724, 747, 974) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 724, 747, 974 is 1.
Step 1: Since 747 > 724, we apply the division lemma to 747 and 724, to get
747 = 724 x 1 + 23
Step 2: Since the reminder 724 ≠ 0, we apply division lemma to 23 and 724, to get
724 = 23 x 31 + 11
Step 3: We consider the new divisor 23 and the new remainder 11, and apply the division lemma to get
23 = 11 x 2 + 1
We consider the new divisor 11 and the new remainder 1, and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 724 and 747 is 1
Notice that 1 = HCF(11,1) = HCF(23,11) = HCF(724,23) = HCF(747,724) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 974 > 1, we apply the division lemma to 974 and 1, to get
974 = 1 x 974 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 974 is 1
Notice that 1 = HCF(974,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 724, 747, 974?
Answer: HCF of 724, 747, 974 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 724, 747, 974 using Euclid's Algorithm?
Answer: For arbitrary numbers 724, 747, 974 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
