Given numbers are 862, 490, 143, 268
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(862, 490) = 211190
GCD(862, 490) = ( 862 x 490 ) / 211190
= 862 / 490
= 862
Step2:
LCM(2, 143) = 286
GCD(2, 143) = ( 2 x 143 ) / 286
= 2 / 143
= 2
Step3:
LCM(1, 268) = 268
GCD(1, 268) = ( 1 x 268 ) / 268
= 1 / 268
= 1
So, Greatest Common Divisor of 862, 490, 143, 268 is 1
