Given numbers are 130, 248, 513, 189
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(130, 248) = 16120
GCD(130, 248) = ( 130 x 248 ) / 16120
= 130 / 248
= 130
Step2:
LCM(2, 513) = 1026
GCD(2, 513) = ( 2 x 513 ) / 1026
= 2 / 513
= 2
Step3:
LCM(1, 189) = 189
GCD(1, 189) = ( 1 x 189 ) / 189
= 1 / 189
= 1
So, Greatest Common Divisor of 130, 248, 513, 189 is 1
