Given numbers are 649, 260, 409, 776
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 260) = 168740
GCD(649, 260) = ( 649 x 260 ) / 168740
= 649 / 260
= 649
Step2:
LCM(1, 409) = 409
GCD(1, 409) = ( 1 x 409 ) / 409
= 1 / 409
= 1
Step3:
LCM(1, 776) = 776
GCD(1, 776) = ( 1 x 776 ) / 776
= 1 / 776
= 1
So, Greatest Common Divisor of 649, 260, 409, 776 is 1
