Given numbers are 312, 453, 508, 640
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(312, 453) = 47112
GCD(312, 453) = ( 312 x 453 ) / 47112
= 312 / 453
= 312
Step2:
LCM(3, 508) = 1524
GCD(3, 508) = ( 3 x 508 ) / 1524
= 3 / 508
= 3
Step3:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
So, Greatest Common Divisor of 312, 453, 508, 640 is 1
