Given numbers are 486, 394, 840, 545
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(486, 394) = 95742
GCD(486, 394) = ( 486 x 394 ) / 95742
= 486 / 394
= 486
Step2:
LCM(2, 840) = 840
GCD(2, 840) = ( 2 x 840 ) / 840
= 2 / 840
= 2
Step3:
LCM(2, 545) = 1090
GCD(2, 545) = ( 2 x 545 ) / 1090
= 2 / 545
= 2
So, Greatest Common Divisor of 486, 394, 840, 545 is 1
