HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 720, 871, 892 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 720, 871, 892 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 720, 871, 892 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 720, 871, 892 is 1.
HCF(720, 871, 892) = 1
HCF of 720, 871, 892 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 720, 871, 892 is 1.
Highest Common Factor of 720,871,892 is 1
Step 1: Since 871 > 720, we apply the division lemma to 871 and 720, to get
871 = 720 x 1 + 151
Step 2: Since the reminder 720 ≠ 0, we apply division lemma to 151 and 720, to get
720 = 151 x 4 + 116
Step 3: We consider the new divisor 151 and the new remainder 116, and apply the division lemma to get
151 = 116 x 1 + 35
We consider the new divisor 116 and the new remainder 35,and apply the division lemma to get
116 = 35 x 3 + 11
We consider the new divisor 35 and the new remainder 11,and apply the division lemma to get
35 = 11 x 3 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 720 and 871 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(35,11) = HCF(116,35) = HCF(151,116) = HCF(720,151) = HCF(871,720) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 892 > 1, we apply the division lemma to 892 and 1, to get
892 = 1 x 892 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 892 is 1
Notice that 1 = HCF(892,1) .
