Given numbers are 648, 420, 441, 288
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 420) = 22680
GCD(648, 420) = ( 648 x 420 ) / 22680
= 648 / 420
= 648
Step2:
LCM(12, 441) = 1764
GCD(12, 441) = ( 12 x 441 ) / 1764
= 12 / 441
= 12
Step3:
LCM(3, 288) = 288
GCD(3, 288) = ( 3 x 288 ) / 288
= 3 / 288
= 3
So, Greatest Common Divisor of 648, 420, 441, 288 is 3
