Given numbers are 658, 992, 981, 181

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

Apply this formula for all numbers.

Step1:

LCM(658, 992) = 326368

GCD(658, 992) = ( 658 x 992 ) / 326368

= 658 / 992

= 658

Step2:

LCM(2, 981) = 1962

GCD(2, 981) = ( 2 x 981 ) / 1962

= 2 / 981

= 2

Step3:

LCM(1, 181) = 181

GCD(1, 181) = ( 1 x 181 ) / 181

= 1 / 181

= 1

So, Greatest Common Divisor of 658, 992, 981, 181 is 1
