Given numbers are 648, 384, 905, 253
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 384) = 10368
GCD(648, 384) = ( 648 x 384 ) / 10368
= 648 / 384
= 648
Step2:
LCM(24, 905) = 21720
GCD(24, 905) = ( 24 x 905 ) / 21720
= 24 / 905
= 24
Step3:
LCM(1, 253) = 253
GCD(1, 253) = ( 1 x 253 ) / 253
= 1 / 253
= 1
So, Greatest Common Divisor of 648, 384, 905, 253 is 1
