Given numbers are 576, 166, 642, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(576, 166) = 47808
GCD(576, 166) = ( 576 x 166 ) / 47808
= 576 / 166
= 576
Step2:
LCM(2, 642) = 642
GCD(2, 642) = ( 2 x 642 ) / 642
= 2 / 642
= 2
Step3:
LCM(2, 455) = 910
GCD(2, 455) = ( 2 x 455 ) / 910
= 2 / 455
= 2
So, Greatest Common Divisor of 576, 166, 642, 455 is 1
