Given numbers are 145, 987, 475, 904
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(145, 987) = 143115
GCD(145, 987) = ( 145 x 987 ) / 143115
= 145 / 987
= 145
Step2:
LCM(1, 475) = 475
GCD(1, 475) = ( 1 x 475 ) / 475
= 1 / 475
= 1
Step3:
LCM(1, 904) = 904
GCD(1, 904) = ( 1 x 904 ) / 904
= 1 / 904
= 1
So, Greatest Common Divisor of 145, 987, 475, 904 is 1
