Given numbers are 513, 408, 608, 981
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(513, 408) = 69768
GCD(513, 408) = ( 513 x 408 ) / 69768
= 513 / 408
= 513
Step2:
LCM(3, 608) = 1824
GCD(3, 608) = ( 3 x 608 ) / 1824
= 3 / 608
= 3
Step3:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
So, Greatest Common Divisor of 513, 408, 608, 981 is 1
