HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 149, 261, 572 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 149, 261, 572 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 149, 261, 572 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 149, 261, 572 is 1.
HCF(149, 261, 572) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 149, 261, 572 is 1.
Step 1: Since 261 > 149, we apply the division lemma to 261 and 149, to get
261 = 149 x 1 + 112
Step 2: Since the reminder 149 ≠ 0, we apply division lemma to 112 and 149, to get
149 = 112 x 1 + 37
Step 3: We consider the new divisor 112 and the new remainder 37, and apply the division lemma to get
112 = 37 x 3 + 1
We consider the new divisor 37 and the new remainder 1, and apply the division lemma to get
37 = 1 x 37 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 149 and 261 is 1
Notice that 1 = HCF(37,1) = HCF(112,37) = HCF(149,112) = HCF(261,149) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 572 > 1, we apply the division lemma to 572 and 1, to get
572 = 1 x 572 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 572 is 1
Notice that 1 = HCF(572,1) .
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 149, 261, 572?
Answer: HCF of 149, 261, 572 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 149, 261, 572 using Euclid's Algorithm?
Answer: For arbitrary numbers 149, 261, 572 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
