Steps to Calculate GCD of 402, 971, 538, 781 using LCM Formula

Given numbers are 402, 971, 538, 781

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

Apply this formula for all numbers.

Step1:

LCM(402, 971) = 390342

GCD(402, 971) = ( 402 x 971 ) / 390342

= 402 / 971

= 402


Step2:

LCM(1, 538) = 538

GCD(1, 538) = ( 1 x 538 ) / 538

= 1 / 538

= 1


Step3:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1


So, Greatest Common Divisor of 402, 971, 538, 781 is 1
