Given numbers are 490, 305, 190, 664
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(490, 305) = 29890
GCD(490, 305) = ( 490 x 305 ) / 29890
= 490 / 305
= 490
Step2:
LCM(5, 190) = 190
GCD(5, 190) = ( 5 x 190 ) / 190
= 5 / 190
= 5
Step3:
LCM(5, 664) = 3320
GCD(5, 664) = ( 5 x 664 ) / 3320
= 5 / 664
= 5
So, Greatest Common Divisor of 490, 305, 190, 664 is 1
