HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2118, 7099, 28425 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 2118, 7099, 28425 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 2118, 7099, 28425 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 2118, 7099, 28425 is 1.
HCF(2118, 7099, 28425) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 2118, 7099, 28425 is 1.
Step 1: Since 7099 > 2118, we apply the division lemma to 7099 and 2118, to get
7099 = 2118 x 3 + 745
Step 2: Since the reminder 2118 ≠ 0, we apply division lemma to 745 and 2118, to get
2118 = 745 x 2 + 628
Step 3: We consider the new divisor 745 and the new remainder 628, and apply the division lemma to get
745 = 628 x 1 + 117
We consider the new divisor 628 and the new remainder 117,and apply the division lemma to get
628 = 117 x 5 + 43
We consider the new divisor 117 and the new remainder 43,and apply the division lemma to get
117 = 43 x 2 + 31
We consider the new divisor 43 and the new remainder 31,and apply the division lemma to get
43 = 31 x 1 + 12
We consider the new divisor 31 and the new remainder 12,and apply the division lemma to get
31 = 12 x 2 + 7
We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get
12 = 7 x 1 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 2118 and 7099 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(31,12) = HCF(43,31) = HCF(117,43) = HCF(628,117) = HCF(745,628) = HCF(2118,745) = HCF(7099,2118) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 28425 > 1, we apply the division lemma to 28425 and 1, to get
28425 = 1 x 28425 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 28425 is 1
Notice that 1 = HCF(28425,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
