HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 871, 779, 728 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 871, 779, 728 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 871, 779, 728 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 871, 779, 728 is 1.
HCF(871, 779, 728) = 1
HCF of 871, 779, 728 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 871, 779, 728 is 1.
Highest Common Factor of 871,779,728 is 1
Step 1: Since 871 > 779, we apply the division lemma to 871 and 779, to get
871 = 779 x 1 + 92
Step 2: Since the reminder 779 ≠ 0, we apply division lemma to 92 and 779, to get
779 = 92 x 8 + 43
Step 3: We consider the new divisor 92 and the new remainder 43, and apply the division lemma to get
92 = 43 x 2 + 6
We consider the new divisor 43 and the new remainder 6,and apply the division lemma to get
43 = 6 x 7 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 871 and 779 is 1
Notice that 1 = HCF(6,1) = HCF(43,6) = HCF(92,43) = HCF(779,92) = HCF(871,779) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 728 > 1, we apply the division lemma to 728 and 1, to get
728 = 1 x 728 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 728 is 1
Notice that 1 = HCF(728,1) .
