HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 145, 273, 395 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 145, 273, 395 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 145, 273, 395 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 145, 273, 395 is 1.
HCF(145, 273, 395) = 1
HCF of 145, 273, 395 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 145, 273, 395 is 1.
Highest Common Factor of 145,273,395 is 1
Step 1: Since 273 > 145, we apply the division lemma to 273 and 145, to get
273 = 145 x 1 + 128
Step 2: Since the reminder 145 ≠ 0, we apply division lemma to 128 and 145, to get
145 = 128 x 1 + 17
Step 3: We consider the new divisor 128 and the new remainder 17, and apply the division lemma to get
128 = 17 x 7 + 9
We consider the new divisor 17 and the new remainder 9,and apply the division lemma to get
17 = 9 x 1 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 145 and 273 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(17,9) = HCF(128,17) = HCF(145,128) = HCF(273,145) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 395 > 1, we apply the division lemma to 395 and 1, to get
395 = 1 x 395 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 395 is 1
Notice that 1 = HCF(395,1) .
