Given numbers are 780, 261, 766, 193
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 261) = 67860
GCD(780, 261) = ( 780 x 261 ) / 67860
= 780 / 261
= 780
Step2:
LCM(3, 766) = 2298
GCD(3, 766) = ( 3 x 766 ) / 2298
= 3 / 766
= 3
Step3:
LCM(1, 193) = 193
GCD(1, 193) = ( 1 x 193 ) / 193
= 1 / 193
= 1
So, Greatest Common Divisor of 780, 261, 766, 193 is 1
