Given numbers are 636, 145, 380, 388
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(636, 145) = 92220
GCD(636, 145) = ( 636 x 145 ) / 92220
= 636 / 145
= 636
Step2:
LCM(1, 380) = 380
GCD(1, 380) = ( 1 x 380 ) / 380
= 1 / 380
= 1
Step3:
LCM(1, 388) = 388
GCD(1, 388) = ( 1 x 388 ) / 388
= 1 / 388
= 1
So, Greatest Common Divisor of 636, 145, 380, 388 is 1
