Given numbers are 435, 394, 149, 642

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

Apply this formula for all numbers.

Step1:

LCM(435, 394) = 171390

GCD(435, 394) = ( 435 x 394 ) / 171390

= 435 / 394

= 435

Step2:

LCM(1, 149) = 149

GCD(1, 149) = ( 1 x 149 ) / 149

= 1 / 149

= 1

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 435, 394, 149, 642 is 1
