Given numbers are 218, 415, 356, 531
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(218, 415) = 90470
GCD(218, 415) = ( 218 x 415 ) / 90470
= 218 / 415
= 218
Step2:
LCM(1, 356) = 356
GCD(1, 356) = ( 1 x 356 ) / 356
= 1 / 356
= 1
Step3:
LCM(1, 531) = 531
GCD(1, 531) = ( 1 x 531 ) / 531
= 1 / 531
= 1
So, Greatest Common Divisor of 218, 415, 356, 531 is 1
