Given numbers are 280, 387, 346, 511
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 387) = 108360
GCD(280, 387) = ( 280 x 387 ) / 108360
= 280 / 387
= 280
Step2:
LCM(1, 346) = 346
GCD(1, 346) = ( 1 x 346 ) / 346
= 1 / 346
= 1
Step3:
LCM(1, 511) = 511
GCD(1, 511) = ( 1 x 511 ) / 511
= 1 / 511
= 1
So, Greatest Common Divisor of 280, 387, 346, 511 is 1
