Given numbers are 278, 879, 140, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 879) = 244362
GCD(278, 879) = ( 278 x 879 ) / 244362
= 278 / 879
= 278
Step2:
LCM(1, 140) = 140
GCD(1, 140) = ( 1 x 140 ) / 140
= 1 / 140
= 1
Step3:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
So, Greatest Common Divisor of 278, 879, 140, 620 is 1
