Given numbers are 603, 759, 128, 109
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(603, 759) = 152559
GCD(603, 759) = ( 603 x 759 ) / 152559
= 603 / 759
= 603
Step2:
LCM(3, 128) = 384
GCD(3, 128) = ( 3 x 128 ) / 384
= 3 / 128
= 3
Step3:
LCM(1, 109) = 109
GCD(1, 109) = ( 1 x 109 ) / 109
= 1 / 109
= 1
So, Greatest Common Divisor of 603, 759, 128, 109 is 1
