GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 378) = 7560
GCD(280, 378) = ( 280 x 378 ) / 7560
= 280 / 378
= 280
Step2:
LCM(14, 786) = 5502
GCD(14, 786) = ( 14 x 786 ) / 5502
= 14 / 786
= 14
Step3:
LCM(2, 442) = 442
GCD(2, 442) = ( 2 x 442 ) / 442
= 2 / 442
= 2
So, Greatest Common Divisor of 280, 378, 786, 442 is 2
