GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 756) = 9828
GCD(156, 756) = ( 156 x 756 ) / 9828
= 156 / 756
= 156
Step2:
LCM(12, 399) = 1596
GCD(12, 399) = ( 12 x 399 ) / 1596
= 12 / 399
= 12
Step3:
LCM(3, 749) = 2247
GCD(3, 749) = ( 3 x 749 ) / 2247
= 3 / 749
= 3
So, Greatest Common Divisor of 156, 756, 399, 749 is 1
