HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 548, 990 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 548, 990 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 548, 990 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 548, 990 is 2.
HCF(548, 990) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 548, 990 is 2.
Step 1: Since 990 > 548, we apply the division lemma to 990 and 548, to get
990 = 548 x 1 + 442
Step 2: Since the reminder 548 ≠ 0, we apply division lemma to 442 and 548, to get
548 = 442 x 1 + 106
Step 3: We consider the new divisor 442 and the new remainder 106, and apply the division lemma to get
442 = 106 x 4 + 18
We consider the new divisor 106 and the new remainder 18,and apply the division lemma to get
106 = 18 x 5 + 16
We consider the new divisor 18 and the new remainder 16,and apply the division lemma to get
18 = 16 x 1 + 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 548 and 990 is 2
Notice that 2 = HCF(16,2) = HCF(18,16) = HCF(106,18) = HCF(442,106) = HCF(548,442) = HCF(990,548) .
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 548, 990?
Answer: HCF of 548, 990 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 548, 990 using Euclid's Algorithm?
Answer: For arbitrary numbers 548, 990 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
