Given numbers are 390, 447, 139, 859
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 447) = 58110
GCD(390, 447) = ( 390 x 447 ) / 58110
= 390 / 447
= 390
Step2:
LCM(3, 139) = 417
GCD(3, 139) = ( 3 x 139 ) / 417
= 3 / 139
= 3
Step3:
LCM(1, 859) = 859
GCD(1, 859) = ( 1 x 859 ) / 859
= 1 / 859
= 1
So, Greatest Common Divisor of 390, 447, 139, 859 is 1
