Given numbers are 377,232,978,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 377,232,978,220 is 81115320.
Find LCM of 377,232,978,220 with Prime Factorization
2 | 377, 232, 978, 220 |
2 | 377, 116, 489, 110 |
29 | 377, 58, 489, 55 |
13, 2, 489, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 29 x 13 x 2 x 489 x 55 = 81115320
Therefore, the lowest common multiple of 377,232,978,220 is 81115320.
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.
377 x 232 x 978 x 220 = 18818754240
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.
377 : 1, 13, 29, 377
232 : 1, 2, 4, 8, 29, 58, 116, 232
978 : 1, 2, 3, 6, 163, 326, 489, 978
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 377,232,978,220, is 1.
Now, the common factors can be found like this.
377:13x 29
232:2x 2x 2x 29
978:2x 3x 163
220:2x 2x 5x 11
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 2x 29 = 232
Therefore, the value for common factors is 232.
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 = 18818754240/(1x232)
LCM = 18818754240/232
LCM = 81115320
Thus, we can understand that the LCM of 377,232,978,220 is 81115320.
