GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(624, 780) = 3120
GCD(624, 780) = ( 624 x 780 ) / 3120
= 624 / 780
= 624
Step2:
LCM(156, 146) = 11388
GCD(156, 146) = ( 156 x 146 ) / 11388
= 156 / 146
= 156
Step3:
LCM(2, 554) = 554
GCD(2, 554) = ( 2 x 554 ) / 554
= 2 / 554
= 2
So, Greatest Common Divisor of 624, 780, 146, 554 is 2
