Calculate the LCM of 702,434,992,870

Given numbers are 702,434,992,870

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

The LCM of 702,434,992,870 is 353414880.

Find LCM of 702,434,992,870 with Prime Factorization


2 702, 434, 992, 870
3 351, 217, 496, 435
31 117, 217, 496, 145
117, 7, 16, 145

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

2 x 3 x 31 x 117 x 7 x 16 x 145 = 353414880

Therefore, the lowest common multiple of 702,434,992,870 is 353414880.

LCM Formula to Find Lowest Common Multiple of 702,434,992,870

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.

702 x 434 x 992 x 870 = 262940670720

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.

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

434 : 1, 2, 7, 14, 31, 62, 217, 434

992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992

870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 702,434,992,870, is 2.

Now, the common factors can be found like this.

702:2x 3x 3x 3x 13

434:2x 7x 31

992:2x 2x 2x 2x 2x 31

870:2x 3x 5x 29

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 31 = 372

Therefore, the value for common factors is 372.

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 = 262940670720/(2x372)

LCM = 262940670720/744

LCM = 353414880

Thus, we can understand that the LCM of 702,434,992,870 is 353414880.
