Given numbers are 148, 666, 672, 688

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

Apply this formula for all numbers.

Step1:

LCM(148, 666) = 1332

GCD(148, 666) = ( 148 x 666 ) / 1332

= 148 / 666

= 148

Step2:

LCM(74, 672) = 24864

GCD(74, 672) = ( 74 x 672 ) / 24864

= 74 / 672

= 74

Step3:

LCM(2, 688) = 688

GCD(2, 688) = ( 2 x 688 ) / 688

= 2 / 688

= 2

So, Greatest Common Divisor of 148, 666, 672, 688 is 2
