GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(206, 442) = 45526
GCD(206, 442) = ( 206 x 442 ) / 45526
= 206 / 442
= 206
Step2:
LCM(2, 919) = 1838
GCD(2, 919) = ( 2 x 919 ) / 1838
= 2 / 919
= 2
Step3:
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
= 1 / 457
= 1
So, Greatest Common Divisor of 206, 442, 919, 457 is 1
