HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 437, 559, 40 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 437, 559, 40 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 437, 559, 40 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 437, 559, 40 is 1.
HCF(437, 559, 40) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 437, 559, 40 is 1.
Step 1: Since 559 > 437, we apply the division lemma to 559 and 437, to get
559 = 437 x 1 + 122
Step 2: Since the reminder 437 ≠ 0, we apply division lemma to 122 and 437, to get
437 = 122 x 3 + 71
Step 3: We consider the new divisor 122 and the new remainder 71, and apply the division lemma to get
122 = 71 x 1 + 51
We consider the new divisor 71 and the new remainder 51,and apply the division lemma to get
71 = 51 x 1 + 20
We consider the new divisor 51 and the new remainder 20,and apply the division lemma to get
51 = 20 x 2 + 11
We consider the new divisor 20 and the new remainder 11,and apply the division lemma to get
20 = 11 x 1 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 437 and 559 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(20,11) = HCF(51,20) = HCF(71,51) = HCF(122,71) = HCF(437,122) = HCF(559,437) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 40 > 1, we apply the division lemma to 40 and 1, to get
40 = 1 x 40 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 40 is 1
Notice that 1 = HCF(40,1) .
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 437, 559, 40?
Answer: HCF of 437, 559, 40 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 437, 559, 40 using Euclid's Algorithm?
Answer: For arbitrary numbers 437, 559, 40 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
