Given numbers are 783, 651, 540, 124
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(783, 651) = 169911
GCD(783, 651) = ( 783 x 651 ) / 169911
= 783 / 651
= 783
Step2:
LCM(3, 540) = 540
GCD(3, 540) = ( 3 x 540 ) / 540
= 3 / 540
= 3
Step3:
LCM(3, 124) = 372
GCD(3, 124) = ( 3 x 124 ) / 372
= 3 / 124
= 3
So, Greatest Common Divisor of 783, 651, 540, 124 is 1
