Given numbers are 280, 945, 319, 442
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 945) = 7560
GCD(280, 945) = ( 280 x 945 ) / 7560
= 280 / 945
= 280
Step2:
LCM(35, 319) = 11165
GCD(35, 319) = ( 35 x 319 ) / 11165
= 35 / 319
= 35
Step3:
LCM(1, 442) = 442
GCD(1, 442) = ( 1 x 442 ) / 442
= 1 / 442
= 1
So, Greatest Common Divisor of 280, 945, 319, 442 is 1
