HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 84, 480, 289 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 84, 480, 289 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 84, 480, 289 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 84, 480, 289 is 1.
HCF(84, 480, 289) = 1
HCF of 84, 480, 289 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 84, 480, 289 is 1.
Highest Common Factor of 84,480,289 is 1
Step 1: Since 480 > 84, we apply the division lemma to 480 and 84, to get
480 = 84 x 5 + 60
Step 2: Since the reminder 84 ≠ 0, we apply division lemma to 60 and 84, to get
84 = 60 x 1 + 24
Step 3: We consider the new divisor 60 and the new remainder 24, and apply the division lemma to get
60 = 24 x 2 + 12
We consider the new divisor 24 and the new remainder 12, and apply the division lemma to get
24 = 12 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 84 and 480 is 12
Notice that 12 = HCF(24,12) = HCF(60,24) = HCF(84,60) = HCF(480,84) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 289 > 12, we apply the division lemma to 289 and 12, to get
289 = 12 x 24 + 1
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 1 and 12, to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 12 and 289 is 1
Notice that 1 = HCF(12,1) = HCF(289,12) .
