Given numbers are 658, 242, 146, 787

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

Apply this formula for all numbers.

Step1:

LCM(658, 242) = 79618

GCD(658, 242) = ( 658 x 242 ) / 79618

= 658 / 242

= 658

Step2:

LCM(2, 146) = 146

GCD(2, 146) = ( 2 x 146 ) / 146

= 2 / 146

= 2

Step3:

LCM(2, 787) = 1574

GCD(2, 787) = ( 2 x 787 ) / 1574

= 2 / 787

= 2

So, Greatest Common Divisor of 658, 242, 146, 787 is 1
