HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 272, 145, 55 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 272, 145, 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, 145, 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, 145, 55 is 1.
HCF(272, 145, 55) = 1
HCF of 272, 145, 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, 145, 55 is 1.
Highest Common Factor of 272,145,55 is 1
Step 1: Since 272 > 145, we apply the division lemma to 272 and 145, to get
272 = 145 x 1 + 127
Step 2: Since the reminder 145 ≠ 0, we apply division lemma to 127 and 145, to get
145 = 127 x 1 + 18
Step 3: We consider the new divisor 127 and the new remainder 18, and apply the division lemma to get
127 = 18 x 7 + 1
We consider the new divisor 18 and the new remainder 1, and apply the division lemma to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 272 and 145 is 1
Notice that 1 = HCF(18,1) = HCF(127,18) = HCF(145,127) = HCF(272,145) .
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) .
