The GCF of 45 and 800 is 5.
The GCF is 5.
Because 45 is not a factor of 60.
The greatest common factor of 45 and 320 is 5.
4.5% of 800= 4.5% * 800= 0.045 * 800= 36
No. 360 is 45% of 800. 350 is 43.75% of 800.
Because 45 is not a factor of 60, whereas 15 and 30 are.
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.
7,200
No, but 5 is a factor of 45.
The greatest common factor of 280 and 800 is 40.
Since 45 is a factor of 270, it is automatically the GCF.
