Tough Question. The answer I got 380 but it is 360.
LCM = 90
Prime factorization of 90 = 2 x 3 x 3 x 5Prime factorization of 120 = 2 x 2 x 2 x 3 x 5HCF(90,120) = 2 x 3 x 5 = 30.LCM of two numbers a and b = Product of a and b/ HCF(a,b)LCM(90,120) = (90 x 120)/30 = 3 x 120 = 360.
The LCM is 10920.
The LCM is 567.
The LCM is 810.
LCM for 90 and 120 is 360.
Least Common Multiple (LCM) for 120 90 is 360.
180
If that's 8, 12 and 10, the LCM is 120. If that's 81 and 210, the LCM is 5670.
1800
The only Least Common Multiple (LCM) for 120 90 is 360.
Write out the multiples of each: 30, 60, 90, 120 40, 80, 120. 120 is the first that appears in both and this is your LCM
81=3x3x3x3 90=3x3 x2x5 ________________ LCM=3x3x3x3x2x5= 810
5 = 5 24 = 23 x 3 8 = 23 LCM = 5 x 23 x 3 = 120
Multiples of 18: {18, 36, 54, 72, 90...}Multiples of 30: {30, 60, 90, 120, 150...}Therefore the LCM is 90.
LCM of 81 and 3 is 81.
