HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 111, 512, 573, 209 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 111, 512, 573, 209 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 111, 512, 573, 209 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 111, 512, 573, 209 is 1.
HCF(111, 512, 573, 209) = 1
HCF of 111, 512, 573, 209 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 111, 512, 573, 209 is 1.
Highest Common Factor of 111,512,573,209 is 1
Step 1: Since 512 > 111, we apply the division lemma to 512 and 111, to get
512 = 111 x 4 + 68
Step 2: Since the reminder 111 ≠ 0, we apply division lemma to 68 and 111, to get
111 = 68 x 1 + 43
Step 3: We consider the new divisor 68 and the new remainder 43, and apply the division lemma to get
68 = 43 x 1 + 25
We consider the new divisor 43 and the new remainder 25,and apply the division lemma to get
43 = 25 x 1 + 18
We consider the new divisor 25 and the new remainder 18,and apply the division lemma to get
25 = 18 x 1 + 7
We consider the new divisor 18 and the new remainder 7,and apply the division lemma to get
18 = 7 x 2 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 111 and 512 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(25,18) = HCF(43,25) = HCF(68,43) = HCF(111,68) = HCF(512,111) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 573 > 1, we apply the division lemma to 573 and 1, to get
573 = 1 x 573 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 573 is 1
Notice that 1 = HCF(573,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 209 > 1, we apply the division lemma to 209 and 1, to get
209 = 1 x 209 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 209 is 1
Notice that 1 = HCF(209,1) .
