Given numbers are 381, 118, 242, 143
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(381, 118) = 44958
GCD(381, 118) = ( 381 x 118 ) / 44958
= 381 / 118
= 381
Step2:
LCM(1, 242) = 242
GCD(1, 242) = ( 1 x 242 ) / 242
= 1 / 242
= 1
Step3:
LCM(1, 143) = 143
GCD(1, 143) = ( 1 x 143 ) / 143
= 1 / 143
= 1
So, Greatest Common Divisor of 381, 118, 242, 143 is 1
