Given numbers are 150, 921, 991, 128

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

Apply this formula for all numbers.

Step1:

LCM(150, 921) = 46050

GCD(150, 921) = ( 150 x 921 ) / 46050

= 150 / 921

= 150

Step2:

LCM(3, 991) = 2973

GCD(3, 991) = ( 3 x 991 ) / 2973

= 3 / 991

= 3

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 150, 921, 991, 128 is 1
