LCM = 30
Explanation:
• Divide the larger number by the smaller number. If it divides exactly then the larger number is the LCM.
• Repeat with multiples of the larger number ( multiply by 2, 3, 4, 5, 6, 7, 8 and 9 ) until exact division is obtained.
#rArr color(red)(15)÷2 color(white)(xxx)X#
#color(red)(15)# is not the LCMNow try the multiple
#2xx15=color(red)(30)#
#rArrcolor(red)(30)÷2 color(white)(xxx) ✔︎#
#rArrcolor(red)(30)# is the LCM.
