Given numbers are 882, 638, 793, 861
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(882, 638) = 281358
GCD(882, 638) = ( 882 x 638 ) / 281358
= 882 / 638
= 882
Step2:
LCM(2, 793) = 1586
GCD(2, 793) = ( 2 x 793 ) / 1586
= 2 / 793
= 2
Step3:
LCM(1, 861) = 861
GCD(1, 861) = ( 1 x 861 ) / 861
= 1 / 861
= 1
So, Greatest Common Divisor of 882, 638, 793, 861 is 1
