Calculate the LCM of 438,262,570,494

Given numbers are 438,262,570,494

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 438,262,570,494 is 70861830.

Find LCM of 438,262,570,494 with Prime Factorization


2 438, 262, 570, 494
3 219, 131, 285, 247
19 73, 131, 95, 247
73, 131, 5, 13

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 19 x 73 x 131 x 5 x 13 = 70861830

Therefore, the lowest common multiple of 438,262,570,494 is 70861830.

LCM Formula to Find Lowest Common Multiple of 438,262,570,494

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.

438 x 262 x 570 x 494 = 32312994480

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.

438 : 1, 2, 3, 6, 73, 146, 219, 438

262 : 1, 2, 131, 262

570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570

494 : 1, 2, 13, 19, 26, 38, 247, 494

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,262,570,494, is 2.

Now, the common factors can be found like this.

438:2x 3x 73

262:2x 131

570:2x 3x 5x 19

494:2x 13x 19

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 19 = 228

Therefore, the value for common factors is 228.

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 = 32312994480/(2x228)

LCM = 32312994480/456

LCM = 70861830

Thus, we can understand that the LCM of 438,262,570,494 is 70861830.
