HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 275, 390, 162 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 275, 390, 162 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 275, 390, 162 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 275, 390, 162 is 1.
HCF(275, 390, 162) = 1
HCF of 275, 390, 162 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 275, 390, 162 is 1.
Highest Common Factor of 275,390,162 is 1
Step 1: Since 390 > 275, we apply the division lemma to 390 and 275, to get
390 = 275 x 1 + 115
Step 2: Since the reminder 275 ≠ 0, we apply division lemma to 115 and 275, to get
275 = 115 x 2 + 45
Step 3: We consider the new divisor 115 and the new remainder 45, and apply the division lemma to get
115 = 45 x 2 + 25
We consider the new divisor 45 and the new remainder 25,and apply the division lemma to get
45 = 25 x 1 + 20
We consider the new divisor 25 and the new remainder 20,and apply the division lemma to get
25 = 20 x 1 + 5
We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 275 and 390 is 5
Notice that 5 = HCF(20,5) = HCF(25,20) = HCF(45,25) = HCF(115,45) = HCF(275,115) = HCF(390,275) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 162 > 5, we apply the division lemma to 162 and 5, to get
162 = 5 x 32 + 2
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get
5 = 2 x 2 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 5 and 162 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(162,5) .
