Steps to Calculate GCD of 919, 689, 291, 780 using LCM Formula

Given numbers are 919, 689, 291, 780

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

Apply this formula for all numbers.

Step1:

LCM(919, 689) = 633191

GCD(919, 689) = ( 919 x 689 ) / 633191

= 919 / 689

= 919


Step2:

LCM(1, 291) = 291

GCD(1, 291) = ( 1 x 291 ) / 291

= 1 / 291

= 1


Step3:

LCM(1, 780) = 780

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

= 1 / 780

= 1
