HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 450, 984, 80 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 450, 984, 80 is 2 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 450, 984, 80 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 450, 984, 80 is 2.
HCF(450, 984, 80) = 2
HCF of 450, 984, 80 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 450, 984, 80 is 2.
Highest Common Factor of 450,984,80 is 2
Step 1: Since 984 > 450, we apply the division lemma to 984 and 450, to get
984 = 450 x 2 + 84
Step 2: Since the reminder 450 ≠ 0, we apply division lemma to 84 and 450, to get
450 = 84 x 5 + 30
Step 3: We consider the new divisor 84 and the new remainder 30, and apply the division lemma to get
84 = 30 x 2 + 24
We consider the new divisor 30 and the new remainder 24,and apply the division lemma to get
30 = 24 x 1 + 6
We consider the new divisor 24 and the new remainder 6,and apply the division lemma to get
24 = 6 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 450 and 984 is 6
Notice that 6 = HCF(24,6) = HCF(30,24) = HCF(84,30) = HCF(450,84) = HCF(984,450) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 80 > 6, we apply the division lemma to 80 and 6, to get
80 = 6 x 13 + 2
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 2 and 6, to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 6 and 80 is 2
Notice that 2 = HCF(6,2) = HCF(80,6) .
