HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 483, 180, 55 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 483, 180, 55 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 483, 180, 55 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 483, 180, 55 is 1.
HCF(483, 180, 55) = 1
HCF of 483, 180, 55 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 483, 180, 55 is 1.
Highest Common Factor of 483,180,55 is 1
Step 1: Since 483 > 180, we apply the division lemma to 483 and 180, to get
483 = 180 x 2 + 123
Step 2: Since the reminder 180 ≠ 0, we apply division lemma to 123 and 180, to get
180 = 123 x 1 + 57
Step 3: We consider the new divisor 123 and the new remainder 57, and apply the division lemma to get
123 = 57 x 2 + 9
We consider the new divisor 57 and the new remainder 9,and apply the division lemma to get
57 = 9 x 6 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 483 and 180 is 3
Notice that 3 = HCF(9,3) = HCF(57,9) = HCF(123,57) = HCF(180,123) = HCF(483,180) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 55 > 3, we apply the division lemma to 55 and 3, to get
55 = 3 x 18 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 55 is 1
Notice that 1 = HCF(3,1) = HCF(55,3) .
