GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(406, 704) = 142912
GCD(406, 704) = ( 406 x 704 ) / 142912
= 406 / 704
= 406
Step2:
LCM(2, 282) = 282
GCD(2, 282) = ( 2 x 282 ) / 282
= 2 / 282
= 2
Step3:
LCM(2, 974) = 974
GCD(2, 974) = ( 2 x 974 ) / 974
= 2 / 974
= 2
So, Greatest Common Divisor of 406, 704, 282, 974 is 2
