Given numbers are 452, 158, 387, 155
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(452, 158) = 35708
GCD(452, 158) = ( 452 x 158 ) / 35708
= 452 / 158
= 452
Step2:
LCM(2, 387) = 774
GCD(2, 387) = ( 2 x 387 ) / 774
= 2 / 387
= 2
Step3:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
So, Greatest Common Divisor of 452, 158, 387, 155 is 1
