HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 450, 364, 801 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 450, 364, 801 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 450, 364, 801 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, 364, 801 is 1.
HCF(450, 364, 801) = 1
HCF of 450, 364, 801 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, 364, 801 is 1.
Highest Common Factor of 450,364,801 is 1
Step 1: Since 450 > 364, we apply the division lemma to 450 and 364, to get
450 = 364 x 1 + 86
Step 2: Since the reminder 364 ≠ 0, we apply division lemma to 86 and 364, to get
364 = 86 x 4 + 20
Step 3: We consider the new divisor 86 and the new remainder 20, and apply the division lemma to get
86 = 20 x 4 + 6
We consider the new divisor 20 and the new remainder 6,and apply the division lemma to get
20 = 6 x 3 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma 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 450 and 364 is 2
Notice that 2 = HCF(6,2) = HCF(20,6) = HCF(86,20) = HCF(364,86) = HCF(450,364) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 801 > 2, we apply the division lemma to 801 and 2, to get
801 = 2 x 400 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 801 is 1
Notice that 1 = HCF(2,1) = HCF(801,2) .
