Given numbers are 278, 526, 840, 123
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 526) = 73114
GCD(278, 526) = ( 278 x 526 ) / 73114
= 278 / 526
= 278
Step2:
LCM(2, 840) = 840
GCD(2, 840) = ( 2 x 840 ) / 840
= 2 / 840
= 2
Step3:
LCM(2, 123) = 246
GCD(2, 123) = ( 2 x 123 ) / 246
= 2 / 123
= 2
So, Greatest Common Divisor of 278, 526, 840, 123 is 1
