The LCM of 697,850,630,625,978 is 8946866250.
Find LCM of 697,850,630,625,978 with Prime Factorization
| 2 | 697, 850, 630, 625, 978 |
| 3 | 697, 425, 315, 625, 489 |
| 5 | 697, 425, 105, 625, 163 |
| 5 | 697, 85, 21, 125, 163 |
| 17 | 697, 17, 21, 25, 163 |
| 41, 1, 21, 25, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 5 x 17 x 41 x 1 x 21 x 25 x 163 = 8946866250
Therefore, the lowest common multiple of 697,850,630,625,978 is 8946866250.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
697 x 850 x 630 x 625 x 978 = 228145089375000
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
697 : 1, 17, 41, 697
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
625 : 1, 5, 25, 125, 625
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,850,630,625,978, is 1.
Now, the common factors can be found like this.
697:17x 41
850:2x 5x 5x 17
630:2x 3x 3x 5x 7
625:5x 5x 5x 5
978:2x 3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 5x 5x 5x 17 = 25500
Therefore, the value for common factors is 25500.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 228145089375000/(1x25500)
LCM = 228145089375000/25500
LCM = 8946866250
Thus, we can understand that the LCM of 697,850,630,625,978 is 8946866250.
