Given numbers are 388, 131, 670, 885
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(388, 131) = 50828
GCD(388, 131) = ( 388 x 131 ) / 50828
= 388 / 131
= 388
Step2:
LCM(1, 670) = 670
GCD(1, 670) = ( 1 x 670 ) / 670
= 1 / 670
= 1
Step3:
LCM(1, 885) = 885
GCD(1, 885) = ( 1 x 885 ) / 885
= 1 / 885
= 1
So, Greatest Common Divisor of 388, 131, 670, 885 is 1
