Given numbers are 130, 135, 561, 393
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(130, 135) = 3510
GCD(130, 135) = ( 130 x 135 ) / 3510
= 130 / 135
= 130
Step2:
LCM(5, 561) = 2805
GCD(5, 561) = ( 5 x 561 ) / 2805
= 5 / 561
= 5
Step3:
LCM(1, 393) = 393
GCD(1, 393) = ( 1 x 393 ) / 393
= 1 / 393
= 1
So, Greatest Common Divisor of 130, 135, 561, 393 is 1
