Given numbers are 145, 140, 921, 656

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

Apply this formula for all numbers.

Step1:

LCM(145, 140) = 4060

GCD(145, 140) = ( 145 x 140 ) / 4060

= 145 / 140

= 145

Step2:

LCM(5, 921) = 4605

GCD(5, 921) = ( 5 x 921 ) / 4605

= 5 / 921

= 5

Step3:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

So, Greatest Common Divisor of 145, 140, 921, 656 is 1
