GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 539) = 22099
GCD(287, 539) = ( 287 x 539 ) / 22099
= 287 / 539
= 287
Step2:
LCM(7, 662) = 4634
GCD(7, 662) = ( 7 x 662 ) / 4634
= 7 / 662
= 7
Step3:
LCM(1, 408) = 408
GCD(1, 408) = ( 1 x 408 ) / 408
= 1 / 408
= 1
So, Greatest Common Divisor of 287, 539, 662, 408 is 1
