Given numbers are 520, 355, 845, 731
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(520, 355) = 36920
GCD(520, 355) = ( 520 x 355 ) / 36920
= 520 / 355
= 520
Step2:
LCM(5, 845) = 845
GCD(5, 845) = ( 5 x 845 ) / 845
= 5 / 845
= 5
Step3:
LCM(5, 731) = 3655
GCD(5, 731) = ( 5 x 731 ) / 3655
= 5 / 731
= 5
So, Greatest Common Divisor of 520, 355, 845, 731 is 1
