Given numbers are 188, 680, 655, 715

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

Apply this formula for all numbers.

Step1:

LCM(188, 680) = 31960

GCD(188, 680) = ( 188 x 680 ) / 31960

= 188 / 680

= 188

Step2:

LCM(4, 655) = 2620

GCD(4, 655) = ( 4 x 655 ) / 2620

= 4 / 655

= 4

Step3:

LCM(1, 715) = 715

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

= 1 / 715

= 1

So, Greatest Common Divisor of 188, 680, 655, 715 is 1
