HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 543, 458, 900, 987 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 543, 458, 900, 987 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 543, 458, 900, 987 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 543, 458, 900, 987 is 1.
HCF(543, 458, 900, 987) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 543, 458, 900, 987 is 1.
Step 1: Since 543 > 458, we apply the division lemma to 543 and 458, to get
543 = 458 x 1 + 85
Step 2: Since the reminder 458 ≠ 0, we apply division lemma to 85 and 458, to get
458 = 85 x 5 + 33
Step 3: We consider the new divisor 85 and the new remainder 33, and apply the division lemma to get
85 = 33 x 2 + 19
We consider the new divisor 33 and the new remainder 19,and apply the division lemma to get
33 = 19 x 1 + 14
We consider the new divisor 19 and the new remainder 14,and apply the division lemma to get
19 = 14 x 1 + 5
We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get
14 = 5 x 2 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 543 and 458 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(19,14) = HCF(33,19) = HCF(85,33) = HCF(458,85) = HCF(543,458) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 900 > 1, we apply the division lemma to 900 and 1, to get
900 = 1 x 900 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 900 is 1
Notice that 1 = HCF(900,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 987 > 1, we apply the division lemma to 987 and 1, to get
987 = 1 x 987 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 987 is 1
Notice that 1 = HCF(987,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
