Given numbers are 741, 651, 20, 243

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

Apply this formula for all numbers.

Step1:

LCM(741, 651) = 160797

GCD(741, 651) = ( 741 x 651 ) / 160797

= 741 / 651

= 741

Step2:

LCM(3, 20) = 60

GCD(3, 20) = ( 3 x 20 ) / 60

= 3 / 20

= 3

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 741, 651, 20, 243 is 1
