Answer» TAKE LCM of Each Number: 90/5=5*2*3*3——————>here we will get one 5 80/5=5*2*2*2*2—————>here we will get one 5 70/5=5*2*7————–___—->here we will get one 5 60/5=5*2*2*3——————>here we will get one 5 50/5=5*5*2___——————>here we will get Two 5^2 40/5=5*2*2*2——————>here we will get one 5 30/5=5*2*3———————>here we will get one 5 20/5=5*2*2———————>here we will get one 5 10/5=5*2————————>here we will get one 5 Here we will get one 5 in each number instead of 50(5*5*2) So answer is 5^10. Take LCM of Each Number: 90/5=5*2*3*3——————>here we will get one 5 80/5=5*2*2*2*2—————>here we will get one 5 70/5=5*2*7————–___—->here we will get one 5 60/5=5*2*2*3——————>here we will get one 5 50/5=5*5*2___——————>here we will get Two 5^2 40/5=5*2*2*2——————>here we will get one 5 30/5=5*2*3———————>here we will get one 5 20/5=5*2*2———————>here we will get one 5 10/5=5*2————————>here we will get one 5 Here we will get one 5 in each number instead of 50(5*5*2) So answer is 5^10. |
