GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 106) = 22684
GCD(428, 106) = ( 428 x 106 ) / 22684
= 428 / 106
= 428
Step2:
LCM(2, 868) = 868
GCD(2, 868) = ( 2 x 868 ) / 868
= 2 / 868
= 2
Step3:
LCM(2, 609) = 1218
GCD(2, 609) = ( 2 x 609 ) / 1218
= 2 / 609
= 2
So, Greatest Common Divisor of 428, 106, 868, 609 is 1
