HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 550, 911, 773 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 550, 911, 773 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 550, 911, 773 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 550, 911, 773 is 1.
HCF(550, 911, 773) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 550, 911, 773 is 1.
Step 1: Since 911 > 550, we apply the division lemma to 911 and 550, to get
911 = 550 x 1 + 361
Step 2: Since the reminder 550 ≠ 0, we apply division lemma to 361 and 550, to get
550 = 361 x 1 + 189
Step 3: We consider the new divisor 361 and the new remainder 189, and apply the division lemma to get
361 = 189 x 1 + 172
We consider the new divisor 189 and the new remainder 172,and apply the division lemma to get
189 = 172 x 1 + 17
We consider the new divisor 172 and the new remainder 17,and apply the division lemma to get
172 = 17 x 10 + 2
We consider the new divisor 17 and the new remainder 2,and apply the division lemma to get
17 = 2 x 8 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 550 and 911 is 1
Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(172,17) = HCF(189,172) = HCF(361,189) = HCF(550,361) = HCF(911,550) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 773 > 1, we apply the division lemma to 773 and 1, to get
773 = 1 x 773 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 773 is 1
Notice that 1 = HCF(773,1) .
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 550, 911, 773?
Answer: HCF of 550, 911, 773 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 550, 911, 773 using Euclid's Algorithm?
Answer: For arbitrary numbers 550, 911, 773 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
