Given numbers are 148, 428, 695, 689

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

Apply this formula for all numbers.

Step1:

LCM(148, 428) = 15836

GCD(148, 428) = ( 148 x 428 ) / 15836

= 148 / 428

= 148

Step2:

LCM(4, 695) = 2780

GCD(4, 695) = ( 4 x 695 ) / 2780

= 4 / 695

= 4

Step3:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

So, Greatest Common Divisor of 148, 428, 695, 689 is 1
