The HCF of 2472, 1284 and a third number N is 12 . If their LCM is 2^(3)xx3^(2)xx5xx103xx107 . Find the number N .

The HCF of 2472, 1284 and a third number N is 12 . If their LCM is 2^(3)xx3^(2)xx5xx103xx107 . Find the number N .

The sum of the H.C.F. and L.C.M of two number is 680 and the L.C.M is 84 times the H.C.F. If one of the numbers is 56 , the other is :

(5^(-3)times a^(3)times c^(4))/(5^(2)times a^(-4)times c^(3))

"(a^(-3)times b^(-2)times c^(-5)times d^(5))/(a^(4)times b times c^(-3)times d^(4))

Evaluate : a^2 times a^4 times b^5 times c^2 times b^2 times c^5

(9^(n)times3^(2)times3^(n)-(27)^(n))/((3^(3))^(5)times2^(3))=(1)/(27)," find the value of "n

H.C.F. xx L.C.M. = Product of two numbers. The L.C.M. and H.C.F. of two numbers is 180 and 6 respectively. If one of the numbers is 30, find the other number.
