Given numbers are 490, 626, 138, 869
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(490, 626) = 153370
GCD(490, 626) = ( 490 x 626 ) / 153370
= 490 / 626
= 490
Step2:
LCM(2, 138) = 138
GCD(2, 138) = ( 2 x 138 ) / 138
= 2 / 138
= 2
Step3:
LCM(2, 869) = 1738
GCD(2, 869) = ( 2 x 869 ) / 1738
= 2 / 869
= 2
So, Greatest Common Divisor of 490, 626, 138, 869 is 1
