HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 519, 61542 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 519, 61542 is 3 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 519, 61542 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 519, 61542 is 3.
HCF(519, 61542) = 3
HCF of 519, 61542 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 519, 61542 is 3.
Highest Common Factor of 519,61542 is 3
Step 1: Since 61542 > 519, we apply the division lemma to 61542 and 519, to get
61542 = 519 x 118 + 300
Step 2: Since the reminder 519 ≠ 0, we apply division lemma to 300 and 519, to get
519 = 300 x 1 + 219
Step 3: We consider the new divisor 300 and the new remainder 219, and apply the division lemma to get
300 = 219 x 1 + 81
We consider the new divisor 219 and the new remainder 81,and apply the division lemma to get
219 = 81 x 2 + 57
We consider the new divisor 81 and the new remainder 57,and apply the division lemma to get
81 = 57 x 1 + 24
We consider the new divisor 57 and the new remainder 24,and apply the division lemma to get
57 = 24 x 2 + 9
We consider the new divisor 24 and the new remainder 9,and apply the division lemma to get
24 = 9 x 2 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 519 and 61542 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(24,9) = HCF(57,24) = HCF(81,57) = HCF(219,81) = HCF(300,219) = HCF(519,300) = HCF(61542,519) .
