GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(890, 290) = 25810
GCD(890, 290) = ( 890 x 290 ) / 25810
= 890 / 290
= 890
Step2:
LCM(10, 668) = 3340
GCD(10, 668) = ( 10 x 668 ) / 3340
= 10 / 668
= 10
Step3:
LCM(2, 462) = 462
GCD(2, 462) = ( 2 x 462 ) / 462
= 2 / 462
= 2
So, Greatest Common Divisor of 890, 290, 668, 462 is 2
