HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 729, 393, 328 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 729, 393, 328 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 729, 393, 328 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, 393, 328 is 1.
HCF(729, 393, 328) = 1
HCF of 729, 393, 328 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, 393, 328 is 1.
Highest Common Factor of 729,393,328 is 1
Step 1: Since 729 > 393, we apply the division lemma to 729 and 393, to get
729 = 393 x 1 + 336
Step 2: Since the reminder 393 ≠ 0, we apply division lemma to 336 and 393, to get
393 = 336 x 1 + 57
Step 3: We consider the new divisor 336 and the new remainder 57, and apply the division lemma to get
336 = 57 x 5 + 51
We consider the new divisor 57 and the new remainder 51,and apply the division lemma to get
57 = 51 x 1 + 6
We consider the new divisor 51 and the new remainder 6,and apply the division lemma to get
51 = 6 x 8 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 729 and 393 is 3
Notice that 3 = HCF(6,3) = HCF(51,6) = HCF(57,51) = HCF(336,57) = HCF(393,336) = HCF(729,393) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 328 > 3, we apply the division lemma to 328 and 3, to get
328 = 3 x 109 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 328 is 1
Notice that 1 = HCF(3,1) = HCF(328,3) .
