Given numbers are 754,639,870,973,632
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 754,639,870,973,632 is 740699636040.
Find LCM of 754,639,870,973,632 with Prime Factorization
| 2 | 754, 639, 870, 973, 632 |
| 3 | 377, 639, 435, 973, 316 |
| 29 | 377, 213, 145, 973, 316 |
| 13, 213, 5, 973, 316 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 13 x 213 x 5 x 973 x 316 = 740699636040
Therefore, the lowest common multiple of 754,639,870,973,632 is 740699636040.
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.
754 x 639 x 870 x 973 x 632 = 257763473341920
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.
754 : 1, 2, 13, 26, 29, 58, 377, 754
639 : 1, 3, 9, 71, 213, 639
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
973 : 1, 7, 139, 973
632 : 1, 2, 4, 8, 79, 158, 316, 632
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 754,639,870,973,632, is 1.
Now, the common factors can be found like this.
754:2x 13x 29
639:3x 3x 71
870:2x 3x 5x 29
973:7x 139
632:2x 2x 2x 79
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 29 = 348
Therefore, the value for common factors is 348.
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 = 257763473341920/(1x348)
LCM = 257763473341920/348
LCM = 740699636040
Thus, we can understand that the LCM of 754,639,870,973,632 is 740699636040.
