HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 390, 746, 324 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 390, 746, 324 is 2 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 390, 746, 324 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 390, 746, 324 is 2.
HCF(390, 746, 324) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 390, 746, 324 is 2.
Step 1: Since 746 > 390, we apply the division lemma to 746 and 390, to get
746 = 390 x 1 + 356
Step 2: Since the reminder 390 ≠ 0, we apply division lemma to 356 and 390, to get
390 = 356 x 1 + 34
Step 3: We consider the new divisor 356 and the new remainder 34, and apply the division lemma to get
356 = 34 x 10 + 16
We consider the new divisor 34 and the new remainder 16,and apply the division lemma to get
34 = 16 x 2 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 390 and 746 is 2
Notice that 2 = HCF(16,2) = HCF(34,16) = HCF(356,34) = HCF(390,356) = HCF(746,390) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 324 > 2, we apply the division lemma to 324 and 2, to get
324 = 2 x 162 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 324 is 2
Notice that 2 = HCF(324,2) .
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 390, 746, 324?
Answer: HCF of 390, 746, 324 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 390, 746, 324 using Euclid's Algorithm?
Answer: For arbitrary numbers 390, 746, 324 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
