Given numbers are 153, 693, 782, 780

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(153, 693) = 11781

GCD(153, 693) = ( 153 x 693 ) / 11781

= 153 / 693

= 153

Step2:

LCM(9, 782) = 7038

GCD(9, 782) = ( 9 x 782 ) / 7038

= 9 / 782

= 9

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 153, 693, 782, 780 is 1
