GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 136) = 39032
GCD(287, 136) = ( 287 x 136 ) / 39032
= 287 / 136
= 287
Step2:
LCM(1, 542) = 542
GCD(1, 542) = ( 1 x 542 ) / 542
= 1 / 542
= 1
Step3:
LCM(1, 392) = 392
GCD(1, 392) = ( 1 x 392 ) / 392
= 1 / 392
= 1
So, Greatest Common Divisor of 287, 136, 542, 392 is 1
