HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 728, 839, 816 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 728, 839, 816 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 728, 839, 816 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 728, 839, 816 is 1.
HCF(728, 839, 816) = 1
HCF of 728, 839, 816 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 728, 839, 816 is 1.
Highest Common Factor of 728,839,816 is 1
Step 1: Since 839 > 728, we apply the division lemma to 839 and 728, to get
839 = 728 x 1 + 111
Step 2: Since the reminder 728 ≠ 0, we apply division lemma to 111 and 728, to get
728 = 111 x 6 + 62
Step 3: We consider the new divisor 111 and the new remainder 62, and apply the division lemma to get
111 = 62 x 1 + 49
We consider the new divisor 62 and the new remainder 49,and apply the division lemma to get
62 = 49 x 1 + 13
We consider the new divisor 49 and the new remainder 13,and apply the division lemma to get
49 = 13 x 3 + 10
We consider the new divisor 13 and the new remainder 10,and apply the division lemma to get
13 = 10 x 1 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 728 and 839 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(49,13) = HCF(62,49) = HCF(111,62) = HCF(728,111) = HCF(839,728) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 816 > 1, we apply the division lemma to 816 and 1, to get
816 = 1 x 816 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 816 is 1
Notice that 1 = HCF(816,1) .
