Given numbers are 228, 555, 357, 685
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(228, 555) = 42180
GCD(228, 555) = ( 228 x 555 ) / 42180
= 228 / 555
= 228
Step2:
LCM(3, 357) = 357
GCD(3, 357) = ( 3 x 357 ) / 357
= 3 / 357
= 3
Step3:
LCM(3, 685) = 2055
GCD(3, 685) = ( 3 x 685 ) / 2055
= 3 / 685
= 3
So, Greatest Common Divisor of 228, 555, 357, 685 is 1
