HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 272, 150, 543, 55 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 272, 150, 543, 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 272, 150, 543, 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 272, 150, 543, 55 is 1.
HCF(272, 150, 543, 55) = 1
HCF of 272, 150, 543, 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 272, 150, 543, 55 is 1.
Highest Common Factor of 272,150,543,55 is 1
Step 1: Since 272 > 150, we apply the division lemma to 272 and 150, to get
272 = 150 x 1 + 122
Step 2: Since the reminder 150 ≠ 0, we apply division lemma to 122 and 150, to get
150 = 122 x 1 + 28
Step 3: We consider the new divisor 122 and the new remainder 28, and apply the division lemma to get
122 = 28 x 4 + 10
We consider the new divisor 28 and the new remainder 10,and apply the division lemma to get
28 = 10 x 2 + 8
We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 272 and 150 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(28,10) = HCF(122,28) = HCF(150,122) = HCF(272,150) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 543 > 2, we apply the division lemma to 543 and 2, to get
543 = 2 x 271 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 543 is 1
Notice that 1 = HCF(2,1) = HCF(543,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 55 > 1, we apply the division lemma to 55 and 1, to get
55 = 1 x 55 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 55 is 1
Notice that 1 = HCF(55,1) .
