Answer:
lcm of a) 810 b) 225 c) 616 d) 693
Step-by-step explanation:
a) LCM(3,81,90)
Least Common Multiple is :
810
Calculate Least Common Multiple for :
3, 81 and 90
Factorize of the above numbers :
3 = 3
81 = 3 power 4
90 = 2 • 32 • 5
b) LCM(15,25,45)
Least Common Multiple is :
225
Calculate Least Common Multiple for :
15, 25 and 45
Factorize of the above numbers :
15 = 3 • 5
25 = 5 power 2
45 = 32 • 5
c) LCM(22,77,88)
Least Common Multiple is :
616
Calculate Least Common Multiple for :
22, 77 and 88
Factorize of the above numbers :
22 = 2 • 11
77 = 7 • 11
88 = 2 power 3 • 11
d) LCM(21,63,99)
Least Common Multiple is :
693
Calculate Least Common Multiple for :
21, 63 and 99
Factorize of the above numbers :
21 = 3 • 7
63 = 3 power 2 • 7
99 = 3 power 2 • 11
