Given numbers are 990, 505, 430, 154
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(990, 505) = 99990
GCD(990, 505) = ( 990 x 505 ) / 99990
= 990 / 505
= 990
Step2:
LCM(5, 430) = 430
GCD(5, 430) = ( 5 x 430 ) / 430
= 5 / 430
= 5
Step3:
LCM(5, 154) = 770
GCD(5, 154) = ( 5 x 154 ) / 770
= 5 / 154
= 5
So, Greatest Common Divisor of 990, 505, 430, 154 is 1
