Given numbers are 721, 282, 827, 490
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(721, 282) = 203322
GCD(721, 282) = ( 721 x 282 ) / 203322
= 721 / 282
= 721
Step2:
LCM(1, 827) = 827
GCD(1, 827) = ( 1 x 827 ) / 827
= 1 / 827
= 1
Step3:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
So, Greatest Common Divisor of 721, 282, 827, 490 is 1
