Given numbers are 477, 155, 469, 621
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(477, 155) = 73935
GCD(477, 155) = ( 477 x 155 ) / 73935
= 477 / 155
= 477
Step2:
LCM(1, 469) = 469
GCD(1, 469) = ( 1 x 469 ) / 469
= 1 / 469
= 1
Step3:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
So, Greatest Common Divisor of 477, 155, 469, 621 is 1
