Given numbers are 768, 206, 438, 555
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(768, 206) = 79104
GCD(768, 206) = ( 768 x 206 ) / 79104
= 768 / 206
= 768
Step2:
LCM(2, 438) = 438
GCD(2, 438) = ( 2 x 438 ) / 438
= 2 / 438
= 2
Step3:
LCM(2, 555) = 1110
GCD(2, 555) = ( 2 x 555 ) / 1110
= 2 / 555
= 2
So, Greatest Common Divisor of 768, 206, 438, 555 is 1
