Given numbers are 752, 645, 66, 139

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

Apply this formula for all numbers.

Step1:

LCM(752, 645) = 485040

GCD(752, 645) = ( 752 x 645 ) / 485040

= 752 / 645

= 752

Step2:

LCM(1, 66) = 66

GCD(1, 66) = ( 1 x 66 ) / 66

= 1 / 66

= 1

Step3:

LCM(1, 139) = 139

GCD(1, 139) = ( 1 x 139 ) / 139

= 1 / 139

= 1

So, Greatest Common Divisor of 752, 645, 66, 139 is 1
