Steps to Calculate GCD of 805, 570, 780, 624 using LCM Formula

Given numbers are 805, 570, 780, 624

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

Apply this formula for all numbers.

Step1:

LCM(805, 570) = 91770

GCD(805, 570) = ( 805 x 570 ) / 91770

= 805 / 570

= 805


Step2:

LCM(5, 780) = 780

GCD(5, 780) = ( 5 x 780 ) / 780

= 5 / 780

= 5


Step3:

LCM(5, 624) = 3120

GCD(5, 624) = ( 5 x 624 ) / 3120

= 5 / 624

= 5


So, Greatest Common Divisor of 805, 570, 780, 624 is 1
