Given numbers are 149, 865, 142, 715

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

Apply this formula for all numbers.

Step1:

LCM(149, 865) = 128885

GCD(149, 865) = ( 149 x 865 ) / 128885

= 149 / 865

= 149

Step2:

LCM(1, 142) = 142

GCD(1, 142) = ( 1 x 142 ) / 142

= 1 / 142

= 1

Step3:

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

= 1 / 715

= 1

So, Greatest Common Divisor of 149, 865, 142, 715 is 1
