Given numbers are 658, 940, 402, 210

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

Apply this formula for all numbers.

Step1:

LCM(658, 940) = 6580

GCD(658, 940) = ( 658 x 940 ) / 6580

= 658 / 940

= 658

Step2:

LCM(94, 402) = 18894

GCD(94, 402) = ( 94 x 402 ) / 18894

= 94 / 402

= 94

Step3:

LCM(2, 210) = 210

GCD(2, 210) = ( 2 x 210 ) / 210

= 2 / 210

= 2

So, Greatest Common Divisor of 658, 940, 402, 210 is 2
