Given numbers are 287, 162, 390, 101
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 162) = 46494
GCD(287, 162) = ( 287 x 162 ) / 46494
= 287 / 162
= 287
Step2:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
Step3:
LCM(1, 101) = 101
GCD(1, 101) = ( 1 x 101 ) / 101
= 1 / 101
= 1
So, Greatest Common Divisor of 287, 162, 390, 101 is 1
