Given numbers are 987, 492, 73, 121

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

Apply this formula for all numbers.

Step1:

LCM(987, 492) = 161868

GCD(987, 492) = ( 987 x 492 ) / 161868

= 987 / 492

= 987

Step2:

LCM(3, 73) = 219

GCD(3, 73) = ( 3 x 73 ) / 219

= 3 / 73

= 3

Step3:

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

= 1 / 121

= 1

So, Greatest Common Divisor of 987, 492, 73, 121 is 1
