Given numbers are 462, 642, 308, 189
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(462, 642) = 49434
GCD(462, 642) = ( 462 x 642 ) / 49434
= 462 / 642
= 462
Step2:
LCM(6, 308) = 924
GCD(6, 308) = ( 6 x 308 ) / 924
= 6 / 308
= 6
Step3:
LCM(2, 189) = 378
GCD(2, 189) = ( 2 x 189 ) / 378
= 2 / 189
= 2
So, Greatest Common Divisor of 462, 642, 308, 189 is 1
