Given numbers are 361, 215, 928, 648
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(361, 215) = 77615
GCD(361, 215) = ( 361 x 215 ) / 77615
= 361 / 215
= 361
Step2:
LCM(1, 928) = 928
GCD(1, 928) = ( 1 x 928 ) / 928
= 1 / 928
= 1
Step3:
LCM(1, 648) = 648
GCD(1, 648) = ( 1 x 648 ) / 648
= 1 / 648
= 1
So, Greatest Common Divisor of 361, 215, 928, 648 is 1
