Given numbers are 747, 543, 420, 575
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(747, 543) = 135207
GCD(747, 543) = ( 747 x 543 ) / 135207
= 747 / 543
= 747
Step2:
LCM(3, 420) = 420
GCD(3, 420) = ( 3 x 420 ) / 420
= 3 / 420
= 3
Step3:
LCM(3, 575) = 1725
GCD(3, 575) = ( 3 x 575 ) / 1725
= 3 / 575
= 3
So, Greatest Common Divisor of 747, 543, 420, 575 is 1
