Given numbers are 260, 120, 555, 434
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(260, 120) = 1560
GCD(260, 120) = ( 260 x 120 ) / 1560
= 260 / 120
= 260
Step2:
LCM(20, 555) = 2220
GCD(20, 555) = ( 20 x 555 ) / 2220
= 20 / 555
= 20
Step3:
LCM(5, 434) = 2170
GCD(5, 434) = ( 5 x 434 ) / 2170
= 5 / 434
= 5
So, Greatest Common Divisor of 260, 120, 555, 434 is 1
