N. .. The H.C.F. and L.C.M. of two numbers are 6 and 2520 respectively. If one of the numbers is 72, find the other number. A. 220 B. 240 C. 120 D. 2106x 2520=72x ? ?= 6x2525/72 ? =210 therefore the other number is 210​

Answer»

HCF = 6
LCM = 2520
a = 72
b = ??
HCF x LCM = product of TWO numbers
HCF x LCM = a x b
6 x 2520 = 72 x b
72 x b = 15120
b = 15120/72
b = 210
Hope it HELPS you
