Given numbers are 408, 220, 975, 313
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 220) = 22440
GCD(408, 220) = ( 408 x 220 ) / 22440
= 408 / 220
= 408
Step2:
LCM(4, 975) = 3900
GCD(4, 975) = ( 4 x 975 ) / 3900
= 4 / 975
= 4
Step3:
LCM(1, 313) = 313
GCD(1, 313) = ( 1 x 313 ) / 313
= 1 / 313
= 1
So, Greatest Common Divisor of 408, 220, 975, 313 is 1
