Given numbers are 820, 198, 124, 681
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 198) = 81180
GCD(820, 198) = ( 820 x 198 ) / 81180
= 820 / 198
= 820
Step2:
LCM(2, 124) = 124
GCD(2, 124) = ( 2 x 124 ) / 124
= 2 / 124
= 2
Step3:
LCM(2, 681) = 1362
GCD(2, 681) = ( 2 x 681 ) / 1362
= 2 / 681
= 2
So, Greatest Common Divisor of 820, 198, 124, 681 is 1
