HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 729, 801, 405 i.e. 9 the largest integer that leaves a remainder zero for all numbers.
HCF of 729, 801, 405 is 9 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 729, 801, 405 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 729, 801, 405 is 9.
HCF(729, 801, 405) = 9
HCF of 729, 801, 405 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 729, 801, 405 is 9.
Highest Common Factor of 729,801,405 is 9
Step 1: Since 801 > 729, we apply the division lemma to 801 and 729, to get
801 = 729 x 1 + 72
Step 2: Since the reminder 729 ≠ 0, we apply division lemma to 72 and 729, to get
729 = 72 x 10 + 9
Step 3: We consider the new divisor 72 and the new remainder 9, and apply the division lemma to get
72 = 9 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 729 and 801 is 9
Notice that 9 = HCF(72,9) = HCF(729,72) = HCF(801,729) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 405 > 9, we apply the division lemma to 405 and 9, to get
405 = 9 x 45 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 9 and 405 is 9
Notice that 9 = HCF(405,9) .
