HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 360, 549, 90 i.e. 9 the largest integer that leaves a remainder zero for all numbers.
HCF of 360, 549, 90 is 9 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 360, 549, 90 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 360, 549, 90 is 9.
HCF(360, 549, 90) = 9
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 360, 549, 90 is 9.
Step 1: Since 549 > 360, we apply the division lemma to 549 and 360, to get
549 = 360 x 1 + 189
Step 2: Since the reminder 360 ≠ 0, we apply division lemma to 189 and 360, to get
360 = 189 x 1 + 171
Step 3: We consider the new divisor 189 and the new remainder 171, and apply the division lemma to get
189 = 171 x 1 + 18
We consider the new divisor 171 and the new remainder 18,and apply the division lemma to get
171 = 18 x 9 + 9
We consider the new divisor 18 and the new remainder 9,and apply the division lemma to get
18 = 9 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 360 and 549 is 9
Notice that 9 = HCF(18,9) = HCF(171,18) = HCF(189,171) = HCF(360,189) = HCF(549,360) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 90 > 9, we apply the division lemma to 90 and 9, to get
90 = 9 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 9 and 90 is 9
Notice that 9 = HCF(90,9) .
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 360, 549, 90?
Answer: HCF of 360, 549, 90 is 9 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 360, 549, 90 using Euclid's Algorithm?
Answer: For arbitrary numbers 360, 549, 90 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
