As a product of its prime factors: 2*3*3*5*7 = 630
630 has 24 factors.
is the answer (1,2,3,5,6)
The prime factors of 630 are: 2, 3, 5, 7
The factors of 630 are: 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630.
It is: 2*3*3*5*7 = 630
As a product of its prime factors: 2*32*5*7 = 630
-14 and -21
The factors of 630 are 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, and 630.
The easiest factor pairs are ( 1 x 630 ) and ( 10 x 63 ).
180 = 22 x 32 x 5 630 = 2 x 32 x 5 x 7 So the common prime factors are 2, 32 & 5 The hcf of 180 and 630 = 2 x 32 x 5 = 90 (take lowest power of all primes) The LCM of 180 and 630 = 22 x 32 x 5 x 7 = 1260 (take highest power of all primes)
630 has 24 factors: 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, and 630.
