HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 530, 851, 123 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 530, 851, 123 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 530, 851, 123 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 530, 851, 123 is 1.
HCF(530, 851, 123) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 530, 851, 123 is 1.
Step 1: Since 851 > 530, we apply the division lemma to 851 and 530, to get
851 = 530 x 1 + 321
Step 2: Since the reminder 530 ≠ 0, we apply division lemma to 321 and 530, to get
530 = 321 x 1 + 209
Step 3: We consider the new divisor 321 and the new remainder 209, and apply the division lemma to get
321 = 209 x 1 + 112
We consider the new divisor 209 and the new remainder 112,and apply the division lemma to get
209 = 112 x 1 + 97
We consider the new divisor 112 and the new remainder 97,and apply the division lemma to get
112 = 97 x 1 + 15
We consider the new divisor 97 and the new remainder 15,and apply the division lemma to get
97 = 15 x 6 + 7
We consider the new divisor 15 and the new remainder 7,and apply the division lemma to get
15 = 7 x 2 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 530 and 851 is 1
Notice that 1 = HCF(7,1) = HCF(15,7) = HCF(97,15) = HCF(112,97) = HCF(209,112) = HCF(321,209) = HCF(530,321) = HCF(851,530) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 123 > 1, we apply the division lemma to 123 and 1, to get
123 = 1 x 123 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 123 is 1
Notice that 1 = HCF(123,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
