Given numbers are 390, 660, 679, 419
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 660) = 8580
GCD(390, 660) = ( 390 x 660 ) / 8580
= 390 / 660
= 390
Step2:
LCM(30, 679) = 20370
GCD(30, 679) = ( 30 x 679 ) / 20370
= 30 / 679
= 30
Step3:
LCM(1, 419) = 419
GCD(1, 419) = ( 1 x 419 ) / 419
= 1 / 419
= 1
So, Greatest Common Divisor of 390, 660, 679, 419 is 1
