HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 509, 2490 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 509, 2490 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 509, 2490 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 509, 2490 is 1.
HCF(509, 2490) = 1
HCF of 509, 2490 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 509, 2490 is 1.
Highest Common Factor of 509,2490 is 1
Step 1: Since 2490 > 509, we apply the division lemma to 2490 and 509, to get
2490 = 509 x 4 + 454
Step 2: Since the reminder 509 ≠ 0, we apply division lemma to 454 and 509, to get
509 = 454 x 1 + 55
Step 3: We consider the new divisor 454 and the new remainder 55, and apply the division lemma to get
454 = 55 x 8 + 14
We consider the new divisor 55 and the new remainder 14,and apply the division lemma to get
55 = 14 x 3 + 13
We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get
14 = 13 x 1 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 509 and 2490 is 1
Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(55,14) = HCF(454,55) = HCF(509,454) = HCF(2490,509) .
