HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 480, 60, 105 i.e. 15 the largest integer that leaves a remainder zero for all numbers.
HCF of 480, 60, 105 is 15 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 480, 60, 105 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 480, 60, 105 is 15.
HCF(480, 60, 105) = 15
HCF of 480, 60, 105 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 480, 60, 105 is 15.
Highest Common Factor of 480,60,105 is 15
Step 1: Since 480 > 60, we apply the division lemma to 480 and 60, to get
480 = 60 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 60, the HCF of 480 and 60 is 60
Notice that 60 = HCF(480,60) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 105 > 60, we apply the division lemma to 105 and 60, to get
105 = 60 x 1 + 45
Step 2: Since the reminder 60 ≠ 0, we apply division lemma to 45 and 60, to get
60 = 45 x 1 + 15
Step 3: We consider the new divisor 45 and the new remainder 15, and apply the division lemma to get
45 = 15 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 60 and 105 is 15
Notice that 15 = HCF(45,15) = HCF(60,45) = HCF(105,60) .
