Given numbers are 189, 603, 132, 398
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(189, 603) = 12663
GCD(189, 603) = ( 189 x 603 ) / 12663
= 189 / 603
= 189
Step2:
LCM(9, 132) = 396
GCD(9, 132) = ( 9 x 132 ) / 396
= 9 / 132
= 9
Step3:
LCM(3, 398) = 1194
GCD(3, 398) = ( 3 x 398 ) / 1194
= 3 / 398
= 3
So, Greatest Common Divisor of 189, 603, 132, 398 is 1
