Given numbers are 768, 286, 811, 355
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(768, 286) = 109824
GCD(768, 286) = ( 768 x 286 ) / 109824
= 768 / 286
= 768
Step2:
LCM(2, 811) = 1622
GCD(2, 811) = ( 2 x 811 ) / 1622
= 2 / 811
= 2
Step3:
LCM(1, 355) = 355
GCD(1, 355) = ( 1 x 355 ) / 355
= 1 / 355
= 1
So, Greatest Common Divisor of 768, 286, 811, 355 is 1
