Given numbers are 640, 902, 913, 818
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 902) = 288640
GCD(640, 902) = ( 640 x 902 ) / 288640
= 640 / 902
= 640
Step2:
LCM(2, 913) = 1826
GCD(2, 913) = ( 2 x 913 ) / 1826
= 2 / 913
= 2
Step3:
LCM(1, 818) = 818
GCD(1, 818) = ( 1 x 818 ) / 818
= 1 / 818
= 1
So, Greatest Common Divisor of 640, 902, 913, 818 is 1
