Given numbers are 945, 658, 30, 239

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

Apply this formula for all numbers.

Step1:

LCM(945, 658) = 88830

GCD(945, 658) = ( 945 x 658 ) / 88830

= 945 / 658

= 945

Step2:

LCM(7, 30) = 210

GCD(7, 30) = ( 7 x 30 ) / 210

= 7 / 30

= 7

Step3:

LCM(1, 239) = 239

GCD(1, 239) = ( 1 x 239 ) / 239

= 1 / 239

= 1

So, Greatest Common Divisor of 945, 658, 30, 239 is 1
