GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(388, 216) = 20952
GCD(388, 216) = ( 388 x 216 ) / 20952
= 388 / 216
= 388
Step2:
LCM(4, 849) = 3396
GCD(4, 849) = ( 4 x 849 ) / 3396
= 4 / 849
= 4
Step3:
LCM(1, 654) = 654
GCD(1, 654) = ( 1 x 654 ) / 654
= 1 / 654
= 1
So, Greatest Common Divisor of 388, 216, 849, 654 is 1
