Steps to Calculate GCD of 778, 681, 623, 562 using LCM Formula

Given numbers are 778, 681, 623, 562

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

Apply this formula for all numbers.

Step1:

LCM(778, 681) = 529818

GCD(778, 681) = ( 778 x 681 ) / 529818

= 778 / 681

= 778


Step2:

LCM(1, 623) = 623

GCD(1, 623) = ( 1 x 623 ) / 623

= 1 / 623

= 1


Step3:

LCM(1, 562) = 562

GCD(1, 562) = ( 1 x 562 ) / 562

= 1 / 562

= 1
