Given numbers are 390, 139, 921, 541

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(390, 139) = 54210

GCD(390, 139) = ( 390 x 139 ) / 54210

= 390 / 139

= 390

Step2:

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

= 1 / 921

= 1

Step3:

LCM(1, 541) = 541

GCD(1, 541) = ( 1 x 541 ) / 541

= 1 / 541

= 1

So, Greatest Common Divisor of 390, 139, 921, 541 is 1
