Given numbers are 378, 133, 374, 390
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(378, 133) = 7182
GCD(378, 133) = ( 378 x 133 ) / 7182
= 378 / 133
= 378
Step2:
LCM(7, 374) = 2618
GCD(7, 374) = ( 7 x 374 ) / 2618
= 7 / 374
= 7
Step3:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
So, Greatest Common Divisor of 378, 133, 374, 390 is 1
