Given numbers are 297, 649, 409, 740
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(297, 649) = 17523
GCD(297, 649) = ( 297 x 649 ) / 17523
= 297 / 649
= 297
Step2:
LCM(11, 409) = 4499
GCD(11, 409) = ( 11 x 409 ) / 4499
= 11 / 409
= 11
Step3:
LCM(1, 740) = 740
GCD(1, 740) = ( 1 x 740 ) / 740
= 1 / 740
= 1
So, Greatest Common Divisor of 297, 649, 409, 740 is 1
