The Greatest Common Factor (GCF) is: 25
The greatest common factor of 45 and 320 is 5.
Greatest common factor of two numbers x and y(x>y) is always less than or equal to y.So, we will write down only those factors of 800 which are less than or equal to 45.Factors of 45: 1, 3, 5, 9, 15 and 45.Factors of 800: 1, 2, 4, 5, 8, 10, 16, 20, 25, 40...So, Greatest common factor is 5.Alternate Method:Method of prime factorization:45 = 3x3x5800 = 2x2x2x2x2x5x5It is clear that 5 is the only number which divides both 45 and 800.So, gcf of 45 and 800 is 5.
GCF(750 g, 600 g, 1.05 kg) = GCF(750, 600, 1050) grams = 150 g.
The LCM of 240 and 800 is 2400.
