GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 387) = 27864
GCD(648, 387) = ( 648 x 387 ) / 27864
= 648 / 387
= 648
Step2:
LCM(9, 282) = 846
GCD(9, 282) = ( 9 x 282 ) / 846
= 9 / 282
= 9
Step3:
LCM(3, 470) = 1410
GCD(3, 470) = ( 3 x 470 ) / 1410
= 3 / 470
= 3
So, Greatest Common Divisor of 648, 387, 282, 470 is 1
