Steps to Calculate GCD of 77, 66, 62, 57 using LCM Formula

Given numbers are 77, 66, 62, 57

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

Apply this formula for all numbers.

Step1:

LCM(77, 66) = 462

GCD(77, 66) = ( 77 x 66 ) / 462

= 77 / 66

= 77


Step2:

LCM(11, 62) = 682

GCD(11, 62) = ( 11 x 62 ) / 682

= 11 / 62

= 11


Step3:

LCM(1, 57) = 57

GCD(1, 57) = ( 1 x 57 ) / 57

= 1 / 57

= 1


So, Greatest Common Divisor of 77, 66, 62, 57 is 1
