Given numbers are 212, 890, 458, 321
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(212, 890) = 94340
GCD(212, 890) = ( 212 x 890 ) / 94340
= 212 / 890
= 212
Step2:
LCM(2, 458) = 458
GCD(2, 458) = ( 2 x 458 ) / 458
= 2 / 458
= 2
Step3:
LCM(2, 321) = 642
GCD(2, 321) = ( 2 x 321 ) / 642
= 2 / 321
= 2
So, Greatest Common Divisor of 212, 890, 458, 321 is 1
