Given numbers are 987, 801, 473, 139
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 801) = 263529
GCD(987, 801) = ( 987 x 801 ) / 263529
= 987 / 801
= 987
Step2:
LCM(3, 473) = 1419
GCD(3, 473) = ( 3 x 473 ) / 1419
= 3 / 473
= 3
Step3:
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
= 1 / 139
= 1
So, Greatest Common Divisor of 987, 801, 473, 139 is 1
