GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 165) = 35640
GCD(648, 165) = ( 648 x 165 ) / 35640
= 648 / 165
= 648
Step2:
LCM(3, 896) = 2688
GCD(3, 896) = ( 3 x 896 ) / 2688
= 3 / 896
= 3
Step3:
LCM(1, 878) = 878
GCD(1, 878) = ( 1 x 878 ) / 878
= 1 / 878
= 1
So, Greatest Common Divisor of 648, 165, 896, 878 is 1
