GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(490, 612) = 149940
GCD(490, 612) = ( 490 x 612 ) / 149940
= 490 / 612
= 490
Step2:
LCM(2, 154) = 154
GCD(2, 154) = ( 2 x 154 ) / 154
= 2 / 154
= 2
Step3:
LCM(2, 546) = 546
GCD(2, 546) = ( 2 x 546 ) / 546
= 2 / 546
= 2
So, Greatest Common Divisor of 490, 612, 154, 546 is 2
