Given numbers are 484, 990, 415, 156
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(484, 990) = 21780
GCD(484, 990) = ( 484 x 990 ) / 21780
= 484 / 990
= 484
Step2:
LCM(22, 415) = 9130
GCD(22, 415) = ( 22 x 415 ) / 9130
= 22 / 415
= 22
Step3:
LCM(1, 156) = 156
GCD(1, 156) = ( 1 x 156 ) / 156
= 1 / 156
= 1
So, Greatest Common Divisor of 484, 990, 415, 156 is 1
