GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 448) = 17472
GCD(156, 448) = ( 156 x 448 ) / 17472
= 156 / 448
= 156
Step2:
LCM(4, 783) = 3132
GCD(4, 783) = ( 4 x 783 ) / 3132
= 4 / 783
= 4
Step3:
LCM(1, 631) = 631
GCD(1, 631) = ( 1 x 631 ) / 631
= 1 / 631
= 1
So, Greatest Common Divisor of 156, 448, 783, 631 is 1
