Given numbers are 693, 111, 456, 278
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(693, 111) = 25641
GCD(693, 111) = ( 693 x 111 ) / 25641
= 693 / 111
= 693
Step2:
LCM(3, 456) = 456
GCD(3, 456) = ( 3 x 456 ) / 456
= 3 / 456
= 3
Step3:
LCM(3, 278) = 834
GCD(3, 278) = ( 3 x 278 ) / 834
= 3 / 278
= 3
So, Greatest Common Divisor of 693, 111, 456, 278 is 1
