Given numbers are 285, 358, 390, 563
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(285, 358) = 102030
GCD(285, 358) = ( 285 x 358 ) / 102030
= 285 / 358
= 285
Step2:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
Step3:
LCM(1, 563) = 563
GCD(1, 563) = ( 1 x 563 ) / 563
= 1 / 563
= 1
So, Greatest Common Divisor of 285, 358, 390, 563 is 1
