HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 455, 300, 480 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 455, 300, 480 is 5 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 455, 300, 480 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 455, 300, 480 is 5.
HCF(455, 300, 480) = 5
HCF of 455, 300, 480 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 455, 300, 480 is 5.
Highest Common Factor of 455,300,480 is 5
Step 1: Since 455 > 300, we apply the division lemma to 455 and 300, to get
455 = 300 x 1 + 155
Step 2: Since the reminder 300 ≠ 0, we apply division lemma to 155 and 300, to get
300 = 155 x 1 + 145
Step 3: We consider the new divisor 155 and the new remainder 145, and apply the division lemma to get
155 = 145 x 1 + 10
We consider the new divisor 145 and the new remainder 10,and apply the division lemma to get
145 = 10 x 14 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 455 and 300 is 5
Notice that 5 = HCF(10,5) = HCF(145,10) = HCF(155,145) = HCF(300,155) = HCF(455,300) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 480 > 5, we apply the division lemma to 480 and 5, to get
480 = 5 x 96 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 480 is 5
Notice that 5 = HCF(480,5) .
