HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 899, 687, 223, 18 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 899, 687, 223, 18 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 899, 687, 223, 18 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 899, 687, 223, 18 is 1.
HCF(899, 687, 223, 18) = 1
HCF of 899, 687, 223, 18 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 899, 687, 223, 18 is 1.
Highest Common Factor of 899,687,223,18 is 1
Step 1: Since 899 > 687, we apply the division lemma to 899 and 687, to get
899 = 687 x 1 + 212
Step 2: Since the reminder 687 ≠ 0, we apply division lemma to 212 and 687, to get
687 = 212 x 3 + 51
Step 3: We consider the new divisor 212 and the new remainder 51, and apply the division lemma to get
212 = 51 x 4 + 8
We consider the new divisor 51 and the new remainder 8,and apply the division lemma to get
51 = 8 x 6 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 899 and 687 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(51,8) = HCF(212,51) = HCF(687,212) = HCF(899,687) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 223 > 1, we apply the division lemma to 223 and 1, to get
223 = 1 x 223 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 223 is 1
Notice that 1 = HCF(223,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 18 > 1, we apply the division lemma to 18 and 1, to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 18 is 1
Notice that 1 = HCF(18,1) .
