Given numbers are 253, 649, 287, 346
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(253, 649) = 14927
GCD(253, 649) = ( 253 x 649 ) / 14927
= 253 / 649
= 253
Step2:
LCM(11, 287) = 3157
GCD(11, 287) = ( 11 x 287 ) / 3157
= 11 / 287
= 11
Step3:
LCM(1, 346) = 346
GCD(1, 346) = ( 1 x 346 ) / 346
= 1 / 346
= 1
So, Greatest Common Divisor of 253, 649, 287, 346 is 1
