Given numbers are 318, 455, 642, 913
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(318, 455) = 144690
GCD(318, 455) = ( 318 x 455 ) / 144690
= 318 / 455
= 318
Step2:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
Step3:
LCM(1, 913) = 913
GCD(1, 913) = ( 1 x 913 ) / 913
= 1 / 913
= 1
So, Greatest Common Divisor of 318, 455, 642, 913 is 1
