Given numbers are 649, 139, 295, 454
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 139) = 90211
GCD(649, 139) = ( 649 x 139 ) / 90211
= 649 / 139
= 649
Step2:
LCM(1, 295) = 295
GCD(1, 295) = ( 1 x 295 ) / 295
= 1 / 295
= 1
Step3:
LCM(1, 454) = 454
GCD(1, 454) = ( 1 x 454 ) / 454
= 1 / 454
= 1
So, Greatest Common Divisor of 649, 139, 295, 454 is 1
