Given numbers are 455, 540, 490, 788
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 540) = 49140
GCD(455, 540) = ( 455 x 540 ) / 49140
= 455 / 540
= 455
Step2:
LCM(5, 490) = 490
GCD(5, 490) = ( 5 x 490 ) / 490
= 5 / 490
= 5
Step3:
LCM(5, 788) = 3940
GCD(5, 788) = ( 5 x 788 ) / 3940
= 5 / 788
= 5
So, Greatest Common Divisor of 455, 540, 490, 788 is 1
