Given numbers are 730, 412, 122, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(730, 412) = 150380
GCD(730, 412) = ( 730 x 412 ) / 150380
= 730 / 412
= 730
Step2:
LCM(2, 122) = 122
GCD(2, 122) = ( 2 x 122 ) / 122
= 2 / 122
= 2
Step3:
LCM(2, 649) = 1298
GCD(2, 649) = ( 2 x 649 ) / 1298
= 2 / 649
= 2
So, Greatest Common Divisor of 730, 412, 122, 649 is 1
