Given numbers are 139, 630, 390, 580
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(139, 630) = 87570
GCD(139, 630) = ( 139 x 630 ) / 87570
= 139 / 630
= 139
Step2:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
Step3:
LCM(1, 580) = 580
GCD(1, 580) = ( 1 x 580 ) / 580
= 1 / 580
= 1
So, Greatest Common Divisor of 139, 630, 390, 580 is 1
