Calculate the LCM of 638,680,122,978

Given numbers are 638,680,122,978

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

The LCM of 638,680,122,978 is 6470506680.

Find LCM of 638,680,122,978 with Prime Factorization

2	638, 680, 122, 978
	319, 340, 61, 489

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

2 x 319 x 340 x 61 x 489 = 6470506680

LCM Formula to Find Lowest Common Multiple of 638,680,122,978

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.

638 x 680 x 122 x 978 = 51764053440

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

122 : 1, 2, 61, 122

978 : 1, 2, 3, 6, 163, 326, 489, 978

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,680,122,978, is 2.

Now, the common factors can be found like this.

638:2x 11x 29

680:2x 2x 2x 5x 17

122:2x 61

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 2 = 4

Therefore, the value for common factors is 4.

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 = 51764053440/(2x4)

LCM = 51764053440/8

LCM = 6470506680

Thus, we can understand that the LCM of 638,680,122,978 is 6470506680.
