Given numbers are 390, 958, 611, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 958) = 186810
GCD(390, 958) = ( 390 x 958 ) / 186810
= 390 / 958
= 390
Step2:
LCM(2, 611) = 1222
GCD(2, 611) = ( 2 x 611 ) / 1222
= 2 / 611
= 2
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 390, 958, 611, 644 is 1
