Given numbers are 240, 270, 558, 690
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(240, 270) = 2160
GCD(240, 270) = ( 240 x 270 ) / 2160
= 240 / 270
= 240
Step2:
LCM(30, 558) = 2790
GCD(30, 558) = ( 30 x 558 ) / 2790
= 30 / 558
= 30
Step3:
LCM(6, 690) = 690
GCD(6, 690) = ( 6 x 690 ) / 690
= 6 / 690
= 6
So, Greatest Common Divisor of 240, 270, 558, 690 is 6
