Given numbers are 930, 138, 919, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(930, 138) = 21390
GCD(930, 138) = ( 930 x 138 ) / 21390
= 930 / 138
= 930
Step2:
LCM(6, 919) = 5514
GCD(6, 919) = ( 6 x 919 ) / 5514
= 6 / 919
= 6
Step3:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
So, Greatest Common Divisor of 930, 138, 919, 405 is 1
