Steps to Calculate GCD of 783, 827, 981, 402 using LCM Formula
Given numbers are 783, 827, 981, 402
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(783, 827) = 647541
GCD(783, 827) = ( 783 x 827 ) / 647541
= 783 / 827
= 783
Step2:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
Step3:
LCM(1, 402) = 402
GCD(1, 402) = ( 1 x 402 ) / 402
= 1 / 402
= 1
So, Greatest Common Divisor of 783, 827, 981, 402 is 1
