HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 369, 930 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 369, 930 is 3 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 369, 930 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 369, 930 is 3.
HCF(369, 930) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 369, 930 is 3.
Step 1: Since 930 > 369, we apply the division lemma to 930 and 369, to get
930 = 369 x 2 + 192
Step 2: Since the reminder 369 ≠ 0, we apply division lemma to 192 and 369, to get
369 = 192 x 1 + 177
Step 3: We consider the new divisor 192 and the new remainder 177, and apply the division lemma to get
192 = 177 x 1 + 15
We consider the new divisor 177 and the new remainder 15,and apply the division lemma to get
177 = 15 x 11 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 369 and 930 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(177,15) = HCF(192,177) = HCF(369,192) = HCF(930,369) .
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 369, 930?
Answer: HCF of 369, 930 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 369, 930 using Euclid's Algorithm?
Answer: For arbitrary numbers 369, 930 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
