Given numbers are 390, 551, 975, 415
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 551) = 214890
GCD(390, 551) = ( 390 x 551 ) / 214890
= 390 / 551
= 390
Step2:
LCM(1, 975) = 975
GCD(1, 975) = ( 1 x 975 ) / 975
= 1 / 975
= 1
Step3:
LCM(1, 415) = 415
GCD(1, 415) = ( 1 x 415 ) / 415
= 1 / 415
= 1
So, Greatest Common Divisor of 390, 551, 975, 415 is 1
