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

Apply this formula for all numbers.

Step1:

LCM(148, 242) = 17908

GCD(148, 242) = ( 148 x 242 ) / 17908

= 148 / 242

= 148

Step2:

LCM(2, 642) = 642

GCD(2, 642) = ( 2 x 642 ) / 642

= 2 / 642

= 2

Step3:

LCM(2, 530) = 530

GCD(2, 530) = ( 2 x 530 ) / 530

= 2 / 530

= 2

So, Greatest Common Divisor of 148, 242, 642, 530 is 2
