GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(228, 164) = 9348
GCD(228, 164) = ( 228 x 164 ) / 9348
= 228 / 164
= 228
Step2:
LCM(4, 642) = 1284
GCD(4, 642) = ( 4 x 642 ) / 1284
= 4 / 642
= 4
Step3:
LCM(2, 459) = 918
GCD(2, 459) = ( 2 x 459 ) / 918
= 2 / 459
= 2
So, Greatest Common Divisor of 228, 164, 642, 459 is 1
