For 70 it is: 2, 5 and 7 For 90 it is: 2, 3, 3 and 5
Factor them. 2 x 2 x 3 x 7 = 84 2 x 3 x 3 x 5 = 90 Combine the highest amount of each factor. 2 x 2 x 3 x 3 x 5 x 7 = 1260, the LCM
2 x 3 x 3 x 5 = 90
60 = 2 x 2 x 3x 5 126 = 2 x 7 x 3 x 3 154 = 2 x 7 x 11 the greatest common factor is 2 x 2 x 3 x 3 x 5 x 7 x 11 = 154 x 90 x 7= 97020
Prime factors of 90 are 2 x 3 x 3 x 5, or 2 x 32 x 5.
90 times 7 = 630
90 x 7 is 630
90 x 7
90 x 7 = 630 sq ft
(3 x 10000) + (4 x 1000) + (8 x 100) + (9 x 10) + (7 x 1)
22 / 7 x 90 = 282.85714
