HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 730, 432, 357 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 730, 432, 357 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 730, 432, 357 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 730, 432, 357 is 1.
HCF(730, 432, 357) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 730, 432, 357 is 1.
Step 1: Since 730 > 432, we apply the division lemma to 730 and 432, to get
730 = 432 x 1 + 298
Step 2: Since the reminder 432 ≠ 0, we apply division lemma to 298 and 432, to get
432 = 298 x 1 + 134
Step 3: We consider the new divisor 298 and the new remainder 134, and apply the division lemma to get
298 = 134 x 2 + 30
We consider the new divisor 134 and the new remainder 30,and apply the division lemma to get
134 = 30 x 4 + 14
We consider the new divisor 30 and the new remainder 14,and apply the division lemma to get
30 = 14 x 2 + 2
We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 730 and 432 is 2
Notice that 2 = HCF(14,2) = HCF(30,14) = HCF(134,30) = HCF(298,134) = HCF(432,298) = HCF(730,432) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 357 > 2, we apply the division lemma to 357 and 2, to get
357 = 2 x 178 + 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 357 is 1
Notice that 1 = HCF(2,1) = HCF(357,2) .
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 730, 432, 357?
Answer: HCF of 730, 432, 357 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 730, 432, 357 using Euclid's Algorithm?
Answer: For arbitrary numbers 730, 432, 357 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
