Given numbers are 478, 490, 891, 356
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(478, 490) = 117110
GCD(478, 490) = ( 478 x 490 ) / 117110
= 478 / 490
= 478
Step2:
LCM(2, 891) = 1782
GCD(2, 891) = ( 2 x 891 ) / 1782
= 2 / 891
= 2
Step3:
LCM(1, 356) = 356
GCD(1, 356) = ( 1 x 356 ) / 356
= 1 / 356
= 1
So, Greatest Common Divisor of 478, 490, 891, 356 is 1
