Given numbers are 558, 307, 501, 780
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(558, 307) = 171306
GCD(558, 307) = ( 558 x 307 ) / 171306
= 558 / 307
= 558
Step2:
LCM(1, 501) = 501
GCD(1, 501) = ( 1 x 501 ) / 501
= 1 / 501
= 1
Step3:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
So, Greatest Common Divisor of 558, 307, 501, 780 is 1
