What is the greatest common factor of 10, 20, and 50?

Viefleur [7K]

Answer:

Step-by-step explanation:

first you need to find the prime factors of the three numbers

ex:

prime factor of 18= $2*3*3$

prime of 24= $2*2*2*3$

there is one 2 and one 3 in common

greatest common multiple 2*3=6

so the greatest common multiple is ten because it is the only one that can divide between all three evenly.

$10=10/10=1\\20=20/10=2\\50=50/10=5$

so 10 is your answer

2. The Soccer Club is selling T-shirts and washing cars to raise money for a summer trip. Last week, the club raised $292.50 by

Rudik [331]

15x = 292.50

45x = 747.50
Divide 45 from both sides
X= 16.61

1 T-shirt = $ 16.61
