Given numbers are 687, 933, 557, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 933) = 213657
GCD(687, 933) = ( 687 x 933 ) / 213657
= 687 / 933
= 687
Step2:
LCM(3, 557) = 1671
GCD(3, 557) = ( 3 x 557 ) / 1671
= 3 / 557
= 3
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 687, 933, 557, 781 is 1
