Given numbers are 390, 545, 625, 579
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 545) = 42510
GCD(390, 545) = ( 390 x 545 ) / 42510
= 390 / 545
= 390
Step2:
LCM(5, 625) = 625
GCD(5, 625) = ( 5 x 625 ) / 625
= 5 / 625
= 5
Step3:
LCM(5, 579) = 2895
GCD(5, 579) = ( 5 x 579 ) / 2895
= 5 / 579
= 5
So, Greatest Common Divisor of 390, 545, 625, 579 is 1
