Given numbers are 840, 394, 206, 555
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 394) = 165480
GCD(840, 394) = ( 840 x 394 ) / 165480
= 840 / 394
= 840
Step2:
LCM(2, 206) = 206
GCD(2, 206) = ( 2 x 206 ) / 206
= 2 / 206
= 2
Step3:
LCM(2, 555) = 1110
GCD(2, 555) = ( 2 x 555 ) / 1110
= 2 / 555
= 2
So, Greatest Common Divisor of 840, 394, 206, 555 is 1
