Given numbers are 315, 555, 768, 778
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(315, 555) = 11655
GCD(315, 555) = ( 315 x 555 ) / 11655
= 315 / 555
= 315
Step2:
LCM(15, 768) = 3840
GCD(15, 768) = ( 15 x 768 ) / 3840
= 15 / 768
= 15
Step3:
LCM(3, 778) = 2334
GCD(3, 778) = ( 3 x 778 ) / 2334
= 3 / 778
= 3
So, Greatest Common Divisor of 315, 555, 768, 778 is 1
