Given numbers are 689, 155, 452, 432
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(689, 155) = 106795
GCD(689, 155) = ( 689 x 155 ) / 106795
= 689 / 155
= 689
Step2:
LCM(1, 452) = 452
GCD(1, 452) = ( 1 x 452 ) / 452
= 1 / 452
= 1
Step3:
LCM(1, 432) = 432
GCD(1, 432) = ( 1 x 432 ) / 432
= 1 / 432
= 1
So, Greatest Common Divisor of 689, 155, 452, 432 is 1
