The numbers below are the factor pairs of 420 (multiplied together they equal 420) (1, 420) (2, 210) (3, 140) (4, 105) (5, 84) (6, 70) (7, 60) (10, 42) (12, 35) (14, 30) (15, 28) (20, 21)
42, 84, 126, 168, 210, 252, 294, 336, 378, 420, 462, 504, 546, . . .
Equation: x^2+x=420 x^2+x-420=0 Using the quadratic formula, x=(-1+sqrt(1+4*420))/2 x=(-1-sqrt(1+4*420))/2 x=20 or -21
Oh, dude, let's break it down! If X divided by Y equals 420, that means X is 420 times Y. So, technically, X could be any multiple of 420, and Y could be any number that isn't zero. It's like a math riddle, but not really a riddle because the answer is pretty straightforward.
divisors of 10 are 1,2,5 and 10, so highest number that can be divide 10 is 10,10 is also a factor of 420 Hence 10 is the highest common factor of 10 and 420. least multiplier of 420 is 420, also 420 is multiplier of 10 hence LCM is 420
Since 210 is a factor of 420, it is automatically the GCF.
210 is not a multiple of 420. 420 is a multiple of 210.
420 - 210 = 210 630 - 420 = 210 840 - 630 = 210
Half of 420 is 210. To find half of a number, you divide it by 2. In this case, 420 divided by 2 equals 210. This is because division is the inverse operation of multiplication, and dividing by 2 is the same as multiplying by 0.5.
210
420/2 = 210 210/2 = 105
420 acres is 1.6997 square km
210 and 420 have a GCF of 210.
