Steps to Calculate GCD of 891, 158, 628, 402 using LCM Formula

Given numbers are 891, 158, 628, 402

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

Apply this formula for all numbers.

Step1:

LCM(891, 158) = 140778

GCD(891, 158) = ( 891 x 158 ) / 140778

= 891 / 158

= 891


Step2:

LCM(1, 628) = 628

GCD(1, 628) = ( 1 x 628 ) / 628

= 1 / 628

= 1


Step3:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1


So, Greatest Common Divisor of 891, 158, 628, 402 is 1
