Given numbers are 642, 988, 739, 258

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

Apply this formula for all numbers.

Step1:

LCM(642, 988) = 317148

GCD(642, 988) = ( 642 x 988 ) / 317148

= 642 / 988

= 642

Step2:

LCM(2, 739) = 1478

GCD(2, 739) = ( 2 x 739 ) / 1478

= 2 / 739

= 2

Step3:

LCM(1, 258) = 258

GCD(1, 258) = ( 1 x 258 ) / 258

= 1 / 258

= 1

So, Greatest Common Divisor of 642, 988, 739, 258 is 1
