Steps to Calculate GCD of 145, 441, 620, 656 using LCM Formula

Given numbers are 145, 441, 620, 656

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

Apply this formula for all numbers.

Step1:

LCM(145, 441) = 63945

GCD(145, 441) = ( 145 x 441 ) / 63945

= 145 / 441

= 145


Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1


Step3:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1


So, Greatest Common Divisor of 145, 441, 620, 656 is 1
