Given numbers are 868, 648, 216, 388
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(868, 648) = 140616
GCD(868, 648) = ( 868 x 648 ) / 140616
= 868 / 648
= 868
Step2:
LCM(4, 216) = 216
GCD(4, 216) = ( 4 x 216 ) / 216
= 4 / 216
= 4
Step3:
LCM(4, 388) = 388
GCD(4, 388) = ( 4 x 388 ) / 388
= 4 / 388
= 4
So, Greatest Common Divisor of 868, 648, 216, 388 is 4
