HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 487, 839, 220, 75 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 487, 839, 220, 75 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 487, 839, 220, 75 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 487, 839, 220, 75 is 1.
HCF(487, 839, 220, 75) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 487, 839, 220, 75 is 1.
Step 1: Since 839 > 487, we apply the division lemma to 839 and 487, to get
839 = 487 x 1 + 352
Step 2: Since the reminder 487 ≠ 0, we apply division lemma to 352 and 487, to get
487 = 352 x 1 + 135
Step 3: We consider the new divisor 352 and the new remainder 135, and apply the division lemma to get
352 = 135 x 2 + 82
We consider the new divisor 135 and the new remainder 82,and apply the division lemma to get
135 = 82 x 1 + 53
We consider the new divisor 82 and the new remainder 53,and apply the division lemma to get
82 = 53 x 1 + 29
We consider the new divisor 53 and the new remainder 29,and apply the division lemma to get
53 = 29 x 1 + 24
We consider the new divisor 29 and the new remainder 24,and apply the division lemma to get
29 = 24 x 1 + 5
We consider the new divisor 24 and the new remainder 5,and apply the division lemma to get
24 = 5 x 4 + 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 487 and 839 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(24,5) = HCF(29,24) = HCF(53,29) = HCF(82,53) = HCF(135,82) = HCF(352,135) = HCF(487,352) = HCF(839,487) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 220 > 1, we apply the division lemma to 220 and 1, to get
220 = 1 x 220 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 220 is 1
Notice that 1 = HCF(220,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 75 > 1, we apply the division lemma to 75 and 1, to get
75 = 1 x 75 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 75 is 1
Notice that 1 = HCF(75,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
