GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 975) = 210600
GCD(648, 975) = ( 648 x 975 ) / 210600
= 648 / 975
= 648
Step2:
LCM(3, 939) = 939
GCD(3, 939) = ( 3 x 939 ) / 939
= 3 / 939
= 3
Step3:
LCM(3, 784) = 2352
GCD(3, 784) = ( 3 x 784 ) / 2352
= 3 / 784
= 3
So, Greatest Common Divisor of 648, 975, 939, 784 is 1
