HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 521, 1818 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 521, 1818 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 521, 1818 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 521, 1818 is 1.
HCF(521, 1818) = 1
HCF of 521, 1818 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 521, 1818 is 1.
Highest Common Factor of 521,1818 is 1
Step 1: Since 1818 > 521, we apply the division lemma to 1818 and 521, to get
1818 = 521 x 3 + 255
Step 2: Since the reminder 521 ≠ 0, we apply division lemma to 255 and 521, to get
521 = 255 x 2 + 11
Step 3: We consider the new divisor 255 and the new remainder 11, and apply the division lemma to get
255 = 11 x 23 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 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 521 and 1818 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(255,11) = HCF(521,255) = HCF(1818,521) .
