Given numbers are 648, 504, 889, 399
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 504) = 4536
GCD(648, 504) = ( 648 x 504 ) / 4536
= 648 / 504
= 648
Step2:
LCM(72, 889) = 64008
GCD(72, 889) = ( 72 x 889 ) / 64008
= 72 / 889
= 72
Step3:
LCM(1, 399) = 399
GCD(1, 399) = ( 1 x 399 ) / 399
= 1 / 399
= 1
So, Greatest Common Divisor of 648, 504, 889, 399 is 1
