HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 576, 450, 388 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 576, 450, 388 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 576, 450, 388 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 576, 450, 388 is 2.
HCF(576, 450, 388) = 2
HCF of 576, 450, 388 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 576, 450, 388 is 2.
Highest Common Factor of 576,450,388 is 2
Step 1: Since 576 > 450, we apply the division lemma to 576 and 450, to get
576 = 450 x 1 + 126
Step 2: Since the reminder 450 ≠ 0, we apply division lemma to 126 and 450, to get
450 = 126 x 3 + 72
Step 3: We consider the new divisor 126 and the new remainder 72, and apply the division lemma to get
126 = 72 x 1 + 54
We consider the new divisor 72 and the new remainder 54,and apply the division lemma to get
72 = 54 x 1 + 18
We consider the new divisor 54 and the new remainder 18,and apply the division lemma to get
54 = 18 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 576 and 450 is 18
Notice that 18 = HCF(54,18) = HCF(72,54) = HCF(126,72) = HCF(450,126) = HCF(576,450) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 388 > 18, we apply the division lemma to 388 and 18, to get
388 = 18 x 21 + 10
Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 10 and 18, to get
18 = 10 x 1 + 8
Step 3: We consider the new divisor 10 and the new remainder 8, and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2, and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 18 and 388 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(18,10) = HCF(388,18) .
