HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 829, 728, 802 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 829, 728, 802 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 829, 728, 802 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 829, 728, 802 is 1.
HCF(829, 728, 802) = 1
HCF of 829, 728, 802 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 829, 728, 802 is 1.
Highest Common Factor of 829,728,802 is 1
Step 1: Since 829 > 728, we apply the division lemma to 829 and 728, to get
829 = 728 x 1 + 101
Step 2: Since the reminder 728 ≠ 0, we apply division lemma to 101 and 728, to get
728 = 101 x 7 + 21
Step 3: We consider the new divisor 101 and the new remainder 21, and apply the division lemma to get
101 = 21 x 4 + 17
We consider the new divisor 21 and the new remainder 17,and apply the division lemma to get
21 = 17 x 1 + 4
We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get
17 = 4 x 4 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 829 and 728 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(21,17) = HCF(101,21) = HCF(728,101) = HCF(829,728) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 802 > 1, we apply the division lemma to 802 and 1, to get
802 = 1 x 802 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 802 is 1
Notice that 1 = HCF(802,1) .
