Given numbers are 290, 910, 778, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(290, 910) = 26390
GCD(290, 910) = ( 290 x 910 ) / 26390
= 290 / 910
= 290
Step2:
LCM(10, 778) = 3890
GCD(10, 778) = ( 10 x 778 ) / 3890
= 10 / 778
= 10
Step3:
LCM(2, 921) = 1842
GCD(2, 921) = ( 2 x 921 ) / 1842
= 2 / 921
= 2
So, Greatest Common Divisor of 290, 910, 778, 921 is 1
