GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(354, 189) = 22302
GCD(354, 189) = ( 354 x 189 ) / 22302
= 354 / 189
= 354
Step2:
LCM(3, 530) = 1590
GCD(3, 530) = ( 3 x 530 ) / 1590
= 3 / 530
= 3
Step3:
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
= 1 / 128
= 1
So, Greatest Common Divisor of 354, 189, 530, 128 is 1
