HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 994, 872, 851 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 994, 872, 851 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 994, 872, 851 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 994, 872, 851 is 1.
HCF(994, 872, 851) = 1
HCF of 994, 872, 851 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 994, 872, 851 is 1.
Highest Common Factor of 994,872,851 is 1
Step 1: Since 994 > 872, we apply the division lemma to 994 and 872, to get
994 = 872 x 1 + 122
Step 2: Since the reminder 872 ≠ 0, we apply division lemma to 122 and 872, to get
872 = 122 x 7 + 18
Step 3: We consider the new divisor 122 and the new remainder 18, and apply the division lemma to get
122 = 18 x 6 + 14
We consider the new divisor 18 and the new remainder 14,and apply the division lemma to get
18 = 14 x 1 + 4
We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get
14 = 4 x 3 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 994 and 872 is 2
Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(18,14) = HCF(122,18) = HCF(872,122) = HCF(994,872) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 851 > 2, we apply the division lemma to 851 and 2, to get
851 = 2 x 425 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 851 is 1
Notice that 1 = HCF(2,1) = HCF(851,2) .
