Given numbers are 287, 434, 148, 402

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

Apply this formula for all numbers.

Step1:

LCM(287, 434) = 17794

GCD(287, 434) = ( 287 x 434 ) / 17794

= 287 / 434

= 287

Step2:

LCM(7, 148) = 1036

GCD(7, 148) = ( 7 x 148 ) / 1036

= 7 / 148

= 7

Step3:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

So, Greatest Common Divisor of 287, 434, 148, 402 is 1
