Given numbers are 260, 395, 780, 247
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(260, 395) = 20540
GCD(260, 395) = ( 260 x 395 ) / 20540
= 260 / 395
= 260
Step2:
LCM(5, 780) = 780
GCD(5, 780) = ( 5 x 780 ) / 780
= 5 / 780
= 5
Step3:
LCM(5, 247) = 1235
GCD(5, 247) = ( 5 x 247 ) / 1235
= 5 / 247
= 5
So, Greatest Common Divisor of 260, 395, 780, 247 is 1
