21 and 35
3 x 5 x 7 x 7
1 x 735, 3 x 245, 5 x 147, 7 x 105, 15 x 49, 21 x 35
367.5 x 2 = 735147 x 5 = 735and so on.
735 ÷ 4 = 183.75 Therefore, in reverse: 183.75 x 4 = 735
Obtain the prime factors of both numbers. 450 = 2 x 3 x 3 x 5 x 5 735 = 3 x 5 x 7 x 7 The factors common to both numbers are 3 and 5. The GCF is 3 x 5 = 15
3 x 5 x 7 x 7
1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735: 1 x 735, 3 x 245, 5 x 147, 7 x 105, 15 x 49, 21 x 35Also, 3 x 5 x 7 x 7 = 735
The prime factorization of 735 is 3 x 5 x 7 x 7 or 3*5*7^2
I assume you mean; X^2 - 72X - 735 = 0 The only way I would do this is by the quadratic formula discriminant (-72)^2 - 4(1)(-735) = 8124 and means two real roots X = - b (+/-) sqrt(b^2-4ac)/2a a = 1 b = - 72 c = - 735 X = - (-72) (+/-) sqrt[(-72)^2 - 4(1)(-735)]/2(1) X = 72 (+/-) sqrt(8124)/2 X = [72 (+/-) 2sqrt(2031)]/2 Ugly, but true.
2 x 3 x 3 x 5 x 5 = 450 3 x 5 x 7 x 7 = 735
2 x 3 x 3 x 5 x 5 = 450 3 x 5 x 7 x 7 = 735
No two prime numbers can do that. 2 x 2 x 2 x 2 x 3 = 48
